About this tool
Girls' clothing sizes move through toddler (T) sizes up to about age 4 or 5, then regular numbered kids' sizes, with a junior or women's crossover starting anywhere from about age 12 to 16 depending on the brand. This calculator checks the age you select against typical weight and height ranges for that size, and flags it when measurements suggest a different size fits better.
The reference chart uses common industry weight and height bands similar to what most major brands use as a general guide. Individual brands, and cuts like dresses versus separates, can still run differently, so this is a reliable starting point rather than an exact match for every label.
Frequently asked questions
Should I size up if she is between two sizes?
Yes, in most cases. Growth spurts can happen quickly, so a slightly bigger size gets more wear than one that is already snug.
What is the difference between size 6 and 6X?
6X is a slimmer-cut alternative to a regular size 6 or 7, offered by some brands for a narrower build. It is not offered by every brand, so checking that specific brand's own chart is the most reliable way to decide.
Do all brands use the same size chart?
No. Numbered sizes like 8 or 10 are a general guide, not a fixed standard, so the same number can fit differently across brands, and dresses often run differently than separates within the same brand.
