Sewing patterns are roadmaps that guide you through creating garments and other projects. They contain essential information about fabric needs, cutting instructions, and step-by-step directions.

Types of Sewing Patterns

Commercial Patterns (The Big 4) The “Big 4” commercial pattern companies dominate the traditional pattern market:

  • Simplicity: Known for beginner-friendly designs with clear instructions
  • Butterick: Offers classic and vintage-inspired styles
  • McCall’s: Features trendy, fashion-forward designs
  • Vogue: Provides high-fashion, designer patterns

These patterns come in printed paper envelopes with pre-printed tissue paper pieces you cut and pin to fabric. They typically offer multiple sizes on one pattern sheet and are widely available in craft stores.

Independent Pattern Companies Independent or “indie” pattern companies like Closet Core Patterns, Grainline Studio, and Tilly and the Buttons often provide more detailed instructions and better customer support. They frequently offer both printed and PDF options, with many including video tutorials and online communities for support.

For example, Simplicity 8352 tells you it’s a Simplicity pattern, while the specific number helps you find it in their catalog or online.

Understanding Pattern Measurements and Sizing

How to Measure Yourself for a Sewing Pattern

Taking accurate measurements is crucial for proper fit. You’ll need a flexible measuring tape and preferably someone to help you.

Essential Measurements:

  1. Bust: Measure around the fullest part of your bust
  2. Waist: Measure at your natural waistline (usually the narrowest part)
  3. Hips: Measure around the fullest part of your hips
  4. Back Neck to Waist: For length adjustments

Tips for Accurate Measuring:

  • Wear well-fitting undergarments
  • Stand naturally – don’t suck in your stomach
  • Keep the tape measure snug but not tight
  • Measure over a fitted t-shirt if you prefer
  • Record measurements and keep them handy

Keep track of your measurements with our printable body measurement tracking sheet – perfect for monitoring changes and comparing across different pattern companies.

Taking accurate body measurements is the foundation of successful pattern selection and garment fit. Unlike ready-to-wear clothing that uses approximate size ranges, sewing patterns require precise measurements to ensure your finished garment fits properly. Many beginners make the mistake of choosing pattern sizes based on their usual clothing size, which can result in garments that are too small or poorly fitted.

The key to accurate measuring is understanding which measurements are most important for different types of garments and how to take them consistently. You’ll need a flexible measuring tape and preferably someone to help you, especially for back measurements. Remember to measure over the undergarments you plan to wear with the finished garment

Once you have your accurate measurements, record them and keep them handy for future pattern purchases. Body measurements can change over time, so it’s wise to re-measure yourself every few months or before starting major projects. These measurements will become your personal reference guide, helping you choose the right pattern size and make informed decisions about ease and fit preferences as you develop your sewing skills.

How to Pick Your Size on a Sewing Pattern

Step 1: Compare your measurements to the pattern size chart

Step 2: Choose based on your largest measurement

Step 3: If between sizes, consider the garment type:

  • For fitted garments: choose the smaller size
  • For loose-fitting garments: choose the larger size

What is a Misses Pattern? “Misses” refers to a standard size category for women, typically designed for:

  • 5’5″ to 5’6″ height
  • B-cup bust
  • Standard proportions
  • Sizes typically 6-20

Other categories include Petite (shorter torso and limbs), Plus Size (18 and up), and Miss Petite.

One of the most confusing aspects of sewing for beginners is understanding why pattern sizes seem so much larger than ready-to-wear clothing sizes. This size difference isn’t an error or oversight, it’s the result of different sizing standards that have evolved over decades. Pattern companies have maintained consistent sizing since the 1950s, while ready-to-wear has undergone significant “vanity sizing” changes.

Understanding this difference is crucial for choosing the correct pattern size and avoiding disappointment with fit. The size you wear in store-bought clothes may be 2-4 sizes smaller than your pattern size, and this is completely normal.

This size difference highlights why taking your own measurements is so important when selecting sewing patterns. Don’t be discouraged if your pattern size seems large compared to your usual clothing size, focus on the body measurements and the finished garment measurements to determine fit. Remember, the goal is creating clothes that fit your body perfectly, not fitting into an arbitrary size number.

What Does 45 and 60 Mean on a Sewing Pattern?

These numbers refer to fabric widths:

  • 45″: Standard narrow fabric width (common for quilting cotton, many fashion fabrics)
  • 60″: Wide fabric width (common for home decor fabrics, some fashion fabrics)

How to Tell if Fabric is 45 or 60:

  • Check the fabric bolt label
  • Measure from selvage to selvage
  • Ask the fabric store staff
  • Most quilting cottons are 44-45″
  • Many knits and home decor fabrics are 54-60″

The pattern envelope shows different yardage requirements for each width because you can fit pattern pieces more efficiently on wider fabric.

Preparing Your Sewing Pattern

Should You Trace Sewing Patterns?

When to Trace:

  • Multi-size patterns (to preserve other sizes)
  • Expensive or vintage patterns
  • When making alterations
  • If you plan to make the pattern multiple times

When Not to Trace:

  • Single-size PDF patterns
  • Inexpensive patterns
  • When time is limited
  • For simple test garments

How to Trace a Sewing Pattern for Beginners

Materials Needed:

  • Pattern tracing paper or Swedish tracing paper
  • Fine-tip markers in different colors
  • Rulers
  • Weights or pins

Steps:

  1. Layer the tracing paper over the original pattern
  2. Trace your size line carefully with a fine marker
  3. Transfer all markings including notches, dots, and grainlines
  4. Label each piece with pattern name and piece number
  5. Cut out traced pieces along your marked lines

How to Trace a Pattern Without Cutting It Out

This technique preserves the original pattern completely:

  1. Use pattern weights instead of pins to hold the original pattern flat
  2. Place tracing paper over the pattern piece
  3. Trace around your size without cutting the original
  4. Mark all symbols and construction details
  5. Remove tracing paper and cut out your traced copy

The original pattern remains intact with all sizes available for future use.

The Made to Sew YouTube channel, run by Aneka Truman, provides excellent weekly tutorials specifically designed for dressmaking beginners. Her step-by-step videos break down complex pattern concepts into manageable, easy-to-understand segments

What Do the Little Triangles Mean on a Sewing Pattern?

Triangles are notches – crucial alignment marks that help you match pattern pieces correctly:

  • Single notches (▲): Usually mark front pieces
  • Double notches (▲▲): Usually mark back pieces
  • Triple notches: Special alignment points

How to Cut Notches:

  • Cut outward from the seam allowance (not inward)
  • Make small snips about 1/8″ deep
  • Or mark with chalk and cut small triangles outward

What Do Circles Mean on a Sewing Pattern?

Circles represent construction dots that indicate:

  • Where to start or stop stitching
  • Matching points between pattern pieces
  • Button placement
  • Pocket positions
  • Dart points

Transfer these dots to your fabric using:

  • Tailor’s chalk
  • Washable fabric markers
  • Pin pricks
  • Tracing paper and wheel

Understanding Cut Numbers

“Cut 2” means:

  • Cut two identical pieces from your fabric
  • Often applies to symmetrical pieces like sleeves
  • May specify “Cut 2 on fold” for pieces like backs

“Cut 1” means:

  • Cut one piece only
  • Often for unique pieces like front panels with buttonholes

Fabric Considerations

Reading Fabric Requirements

Pattern envelopes show fabric requirements in a table format:

Size    45" fabric    60" fabric
12      2 1/8 yards   1 7/8 yards
14      2 1/4 yards   2 yards
16      2 3/8 yards   2 1/8 yards

Understanding fabric width is essential for purchasing the correct amount of fabric and planning efficient pattern layouts. Most sewing patterns provide fabric requirements for both 45-inch and 60-inch wide fabrics, but the difference in layout efficiency can be dramatic. Choosing the right fabric width can save you money, reduce waste, and make the cutting process much easier.

Fabric width affects not only how much fabric you need to buy but also how efficiently you can arrange pattern pieces. Wider fabrics often allow for more economical layouts, especially for larger garments, while narrower fabrics may require more strategic planning and additional yardage.

abric width comparison diagram illustrating pattern piece layout on 45-inch and 60-inch wide fabrics with efficiency statistics and yardage requirements table
Visual comparison of 45-inch versus 60-inch fabric widths showing pattern layout efficiency and yardage requirements for different garment types

When shopping for fabric, always check the actual width on the bolt, as measurements can vary slightly from stated widths. Consider both the per-yard cost and the total yardage required when comparing fabrics of different widths. Sometimes a more expensive 60-inch fabric can be more economical overall due to reduced yardage requirements. Understanding these principles will help you make informed fabric choices that suit both your project needs and budget.

How to Calculate How Much Fabric You Need

Basic Formula:

  1. Find your size in the fabric requirements table
  2. Check your fabric width (45″ or 60″)
  3. Add 1/4 to 1/2 yard extra for:
    • Pattern matching (if needed)
    • Mistakes
    • Pre-shrinking allowance

Take the guesswork out of fabric shopping with our fabric requirements calculator that accounts for pattern matching, pre-shrinking, and safety margins.

Selecting Appropriate Fabrics

Pattern envelopes list suggested fabrics for good reason. These recommendations ensure your finished garment will look and behave as intended.

Reading Fabric Suggestions:

  • “Suitable for knits only”: Pattern designed for stretchy fabrics
  • “Woven fabrics”: Pattern designed for non-stretch fabrics
  • “Lightweight to medium weight”: Fabric weight recommendations
  • “No obvious diagonal”: Avoid fabrics with strong directional patterns

For comprehensive fabric information, check our guide to common fabric types and their uses.

What is Nap in a Sewing Pattern?

Nap refers to fabrics with directional properties:

  • Pile fabrics: Velvet, corduroy, fleece
  • Directional prints: One-way patterns, text
  • Brushed fabrics: Some cottons and wools
  • Shiny fabrics: Satin, some silks

With Nap Layout:

  • All pattern pieces face the same direction
  • Requires more fabric (check “with nap” yardage)
  • Ensures consistent color/texture appearance

Understanding Fabric Width Standards

Standard Fabric Widths:

TypeCommon Widths
Quilting Cotton44-45″
Fashion Cotton45″
Linen45-60″
Knits58-60″
Home Decor54-60″
Wool60″

In the UK, standard widths follow similar measurements, though some specialty fabrics may vary.

  2. Press fabric to remove wrinkles
  3. Check fabric width and confirm with pattern requirements
  4. Find the correct layout diagram for your size and fabric width

Grainline and Fabric Direction

Understanding Grainline:

  • Lengthwise grain: Parallel to selvage (strongest)
  • Crosswise grain: Perpendicular to selvage
  • Bias: 45-degree angle to grain (most stretch)

Placing Grainline:

  1. Measure from grainline arrow to selvage at both ends
  2. Ensure measurements are equal
  3. Pin pattern piece securely
  4. Double-check before cutting

For detailed information about fabric direction, see our fabric cutting guide.

How to Pattern Match Fabric for Beginners

For Plaid or Striped Fabrics:

  1. Plan your layout carefully before cutting
  2. Match dominant lines at center front and major seams
  3. Buy extra fabric (usually 1/2 to 1 yard additional)
  4. Use single layer cutting method for precision
  5. Mark pattern pieces to indicate which direction they face

Pattern Matching Tips:

  • Start with the main front piece
  • Match at bust level for tops
  • Match at hip level for skirts
  • Don’t worry about perfect matching at all seams – focus on the most visible areas

Advanced Pattern Concepts

What is the Golden Rule Sewing Pattern System?

The golden rule pattern system uses proportional measurements rather than standard sizing. It calculates all garment dimensions based on your height as the base measurement, creating more personalized fit for individual body proportions.

How it Works:

  • Your height becomes the master measurement
  • All other measurements are calculated as proportions of your height
  • Results in better fit for non-standard proportions
  • Requires fewer adjustments than traditional sizing

What is the Pattern Maker’s Rule?

The pattern maker’s rule refers to basic principles followed when creating patterns:

  1. Ease must be appropriate for the garment type and fabric
  2. Grain direction must support the garment’s function
  3. Balance lines should create visual harmony
  4. Seam allowances must be consistent and appropriate

Three Principles of Pattern Making

  1. Fit: Pattern must accommodate the body with appropriate ease
  2. Function: Pattern must allow for intended use and movement
  3. Fashion: Pattern must create the desired style and silhouette

How to Size Up a Sewing Pattern for Beginners

Simple Sizing Up:

  1. Determine how much larger you need the pattern
  2. Add width evenly at side seams (divide total increase by number of seams)
  3. Maintain proportions at necklines and armholes
  4. Test fit with muslin before cutting final fabric

Complex Alterations:

  • Consider taking a pattern alteration class
  • Use pattern drafting books as reference
  • Start with simple adjustments before attempting major changes

Pattern Organization and Storage

How to Organize Sewing Patterns

Physical Pattern Storage:

  • File folders by pattern company or garment type
  • Clear plastic sleeves to protect envelopes

Seam Allowances and Construction

Understanding Seam Allowances

Most patterns include seam allowances, but the amount varies:

  • 5/8″: Standard for most commercial patterns
  • 1/2″: Common for some indie patterns
  • 1cm: European and some modern patterns
  • None included: Some patterns require you to add seam allowances

Check your pattern instructions to confirm seam allowance amounts. For detailed seam allowance information, visit our seam allowance guide.

How to Grade Seam Allowances

Grading reduces bulk in seam allowances, especially important for:

  • Curved seams
  • Multiple layers
  • Thick fabrics
  • Professional finish

Learn more about this technique in our seam allowance grading guide.

Advanced Techniques and Tips

Working with Stretch Fabrics

When your pattern calls for knits or stretch fabrics:

  • Check stretch percentage: Pattern may specify required stretch
  • Use appropriate needles: Ballpoint or stretch needles
  • Choose correct stitches: Zigzag or stretch stitches
  • Test on scraps: Before sewing final garment

For more information, see our guide to stretchy fabrics.

Professional Finishing Techniques

  • Press as you go: Creates professional-looking results
  • Finish seam edges: Prevents fraying and adds durability
  • Use proper interfacing: Adds structure where needed
  • Hand-finished details: Elevate the final appearance

Pattern Repeat Calculations

For Patterned Fabrics:

  1. Measure the repeat: Distance between pattern repetitions
  2. Calculate additional fabric: Usually one full repeat extra
  3. Plan layout carefully: Match patterns at key points
  4. Buy extra: Better to have too much than too little

  • Fabric Preparation: Pre-wash your fabric and pay careful attention to grainline placement. Understanding fabric width (45″ vs 60″) helps you purchase the correct amount and plan your layout efficiently.
  • Digital vs. Physical: Both PDF and paper patterns have advantages. PDF patterns offer instant gratification and unlimited reprinting, while paper patterns provide convenience and traditional ease of use. Choose based on your preferences and needs.
  • Marking and Symbols: Pattern symbols are universal guidelines that ensure proper construction. Take time to transfer all markings accurately to your fabric – these seemingly small details make the difference between a professional and amateur-looking result.
  • Troubleshooting Mindset: Mistakes are part of the learning process. When issues arise, refer back to the pattern instructions, check online resources, and don’t hesitate to make test garments before cutting expensive fabric.
  • Progressive Skill Building: Start with simple projects and gradually tackle more complex techniques. Each successful project builds confidence and teaches valuable skills that apply to future endeavors.

Final Recommendations

  1. Invest in quality tools: Good scissors, measuring tools, and marking supplies make the process more enjoyable and accurate.
  2. Build a reference library: Keep pattern instructions, save useful tutorials, and maintain notes about successful techniques.
  3. Join the community: Online sewing groups, local classes, and pattern review sites provide support, inspiration, and troubleshooting help.
  4. Practice patience: Rushing through pattern reading and preparation often leads to mistakes that are time-consuming to fix later.
  5. Embrace the learning process: Every pattern teaches something new, whether it’s a construction technique, fit principle, or fabric behavior.

Remember that reading sewing patterns is a skill that improves with practice. Each project you complete makes the next one easier and more enjoyable. The investment you make in learning these fundamentals will pay dividends in every future sewing project, enabling you to create garments that fit well, look professional, and reflect your personal style.

Whether you’re drawn to simple everyday pieces or complex couture techniques, understanding how to read and interpret sewing patterns is your gateway to a lifetime of creative fulfillment. Take your time, be patient with yourself, and enjoy the journey of bringing your sewing visions to life.
