Kyte Baby Baby Size Chart — Fit by Weight & Height
Kyte Baby's published baby-clothing size chart, size by size — the weight and height each label covers, plus how Kyte Baby compares to 30 other brands. Based on Kyte Baby's own published chart (retrieved 2026-09-02); we compare brands' published charts and do not handle or test any garment.
Across its published chart, each Kyte Baby size covers about 0.7 lb less weight than the 30-brand median. If your baby is near the top of a weight range, consider sizing up in Kyte Baby.

Read the “vs median” column to see where Kyte Baby differs: a positive number means that size covers heavier babies than the typical brand (runs bigger on paper); negative means smaller.
How we built this
There is no US standard for baby-clothing sizes, so the same label fits different weights at different brands. This page reproduces Kyte Baby's own published size chart and compares each size to the median of 30 brands from our Baby Clothing Size Index 2026. Figures are from Kyte Baby's published chart (retrieved 2026-09-02); we compare published charts only and never claim to have measured or tested a garment. For clothing fit only — not a guide to how much a baby should weigh.
