Kids sizes, which never stay current for long

Children grow fast, so a saved size stops being true after a while. Specsy keeps the current measurements together with the date they were taken, and reminds you when it is time to measure again.

The number can be right while the date is not

You remember that your son is a 27. But that was February, and it is now September. The foot has had time to grow, and new shoes will be tight in no time.

Childrens clothing is the same: the size often follows height rather than age, so a label saying 5 to 6 years can be less useful than a measurement of 116 cm.

The fix is simple: save the size together with the date it was measured, and set a reminder to check it again — before the season changes, for example.

What to write down for a child

  • Height in centimetres — the main reference for most childrens clothing sizes
  • Foot length — so shoes are easier to pick in any sizing system
  • The date of the measurement — without it even an exact number loses its meaning
  • The outerwear size — if you buy it with room to grow, note why right there
  • School uniform in detail — the size, the exact model, the brand and where it was bought

Roughly how often to check the sizes

Not strict rules, just a rough guide. The point is not to remember it all yourself, but to set a reminder and update the measurements now and then.

AgeHow often to checkWhy
0–1 yearAbout every 2 monthsSizes change very fast
1–3 yearsAbout every 3 monthsFoot length changes fastest of all
4–8 yearsEvery 4–6 monthsGrowth is uneven, and a size can change unexpectedly
9 and olderBefore each seasonA growth spurt can make old measurements useless quickly

What can be bought with room to grow, and what is better true to size

  • Coats and winter gear — a little room rarely hurts: a longer sleeve, space for a warm layer
  • Shoes — better bought to the current foot length than well ahead of it
  • School trousers — room helps if there is an adjustable waist or a hem that can be turned up
  • Swimwear — better true to size, or it will sit far too loose
  • Wellingtons — a little room is fine, especially with a thick sock

Questions people ask

Can Specsy remind me to measure again?

Yes. Set a reminder on the card, for example every four months, and it will appear on your phone.

Can grandparents see the sizes?

Yes. Invite them to the family group and they can look the current sizes up themselves. It helps most before presents: nothing has to be asked, and the surprise survives.

Do I need a separate card for each child?

Yes, one card each works best. In a shop it stays simple: you open the right child and see the sizes, the measurements and the date they were last taken.

Save it once. Find it whenever you need it.
