24M and 2T are not always the same size
Carter’s gives them different height ranges, Garanimals gives them the same one, and Gerber sells one combined 24M / 2T size.

Newborn can overlap 0–3M
Hanna Andersson lists newborn as up to 19 inches and 0–3M as 18–22 inches, so a 18.5-inch baby fits both.

How we built the index
We started from a list of 127 US and Canadian baby and kids’ clothing brands. For 49 of them we found a published size chart with numbers we could read and check. We copied every size exactly as published: the size label, height, weight, chest and waist where given, the chart name, and the link to the page. Each brand’s own chart came first; where a brand’s chart couldn’t be read, we used a retailer’s copy and marked it.
Inches are converted to centimeters (× 2.54) and pounds to kilograms (× 0.45359237). Values given as “up to” or as a single number are kept that way, and nothing missing is filled in.
The size comparisons use only the brands’ own charts for unisex everyday clothing, one chart per brand, and only sizes with a full height range. A size label is compared only when at least three brands publish it. We report the middle of each range and how far apart those middles are. A smaller spread does not mean a brand fits better.
This is a snapshot of published charts, not a fit test or a sizing standard. Charts change, and some products use their own chart, so check the chart on the product page before you buy.

Corrections and updates
- 3 October 2026, release 1.1: before publication we re-checked the data against the brands’ live pages. Carter’s chart names were corrected, New Balance was removed because its tables no longer match New Balance’s official guide, and one unconfirmed Primary size was removed. No comparison results changed.
The index is a dated snapshot. The calculator’s charts are rechecked separately, and later changes to them are listed on How We Check Sizes.
Found a mistake? Email amzad@babysizefinder.com with the brand, size and what the brand’s chart says. We fix confirmed errors and note them here.
