What age is size 146 in kids clothes?
Size 146 is a height size: it is cut for a child about 146 cm (4 ft 9 in) tall. Typical age: 10.9 years to 11.8 years. Closest US size: 10 or 12.
The short answer
In UK and EU kids' clothing the size number is body height in centimetres, so size 146 suits a child about 146 cm tall. A 6 cm step between sizes means one size covers roughly 143 to 149 cm. On the CDC and WHO growth charts the median boy reaches 146 cm at 11.5 years and the median girl at 11.3 years. Children in the 143 to 149 cm band are typically 10.9 years to 11.8 years old. Because children vary a lot, the 3rd to 97th percentile range (the middle 94 percent of children) means a 146 cm child can be anywhere from 9.1 years to 13.7 years. That is typical growth, not a fit guarantee: brands run small or large, and children grow, so size up one bracket for growth room.

Heights at age 11 (CDC/WHO)
For comparison, the middle 94 percent of 11-year-old boys are 131-157 cm (median 144); girls 130-158 cm (median 144). Values are the 3rd to 97th percentile with the 50th percentile (median) in brackets. Percentiles describe how children vary; they are not a health assessment.
How this was worked out
Size 146 is read as height 146 cm. The age at which the median height reaches 146 cm comes from the WHO standards (to age 5) and CDC charts (age 5 and up), linearly interpolated between published points. The "typical" band is the age the pooled boy-and-girl median passes 143 cm to the age it passes 149 cm. The wide range is the age the 97th percentile child is 146 cm to the age the 3rd percentile child is 146 cm. The US size is the age size nearest the pooled median age for 146 cm; US sizes are labelled roughly by age, and the CPSC rules in 16 CFR 1615 and 1616 list size names only, not heights.
Sources and as-of date. Height data: CDC stature-for-age percentile data (2 to 20 years) (CDC growth charts) and WHO Child Growth Standards, length/height-for-age (0 to 5 years). Size designation: the EN 13402 series (ISO 3635 lineage) uses body height in centimetres as the primary dimension for children's clothing. US size names: 16 CFR 1615 and 16 CFR 1616 (CPSC sleepwear rules list sizes 9-12 months up to 14, but give no height chart). Shoe sizing: ISO/TS 19407:2023. Data files read on 2026-10-02.
Frequently asked questions
What age is size 146 in kids UK clothes?
UK and EU kids' sizes are height sizes, so size 146 is cut for a child about 146 cm (4 ft 9 in) tall, not for a set age. By CDC and WHO median heights, children are typically 10.9 years to 11.8 years old when they are 143 to 149 cm tall. Brands print age labels too, and those can differ from this figure, so trust the height.
Should I buy size 146 or size 152?
Measure your child barefoot against a wall. If they are about 146 cm, size 146 fits now; if you want room to grow or the brand runs small, take size 152. Children grow roughly 5 to 7 cm a year between ages 4 and 10, so one size up is usually good for a season.
Is size 146 the same in the US?
Not exactly. US sizes are labelled roughly by age in years, and there is no single public height chart. Matching by the median age for 146 cm gives about size 10 or 12 (14 is the next one up). Check the brand's own chart.
