What the number on kids' trousers actually means
Children's sizing never settled on one system, and Pakistani shelves carry all of them at once — local ready-made brands, school uniform suppliers, and imported stock that was sized for another country's children. Before you compare two trousers, work out what their numbers are counting.
None of these is wrong. The trouble starts when you carry a number from one system into another — ordering a “32” because last year's “32” fitted, when the two shops were measuring different things entirely.
- Age — “8–9 years”, “10–11 years”. The friendliest label and the least precise: two children of the same age can be several inches apart in height.
- Waist in inches — 22, 24, 26. Common on school uniform trousers, where the waist is what the belt has to hold.
- Length in inches — 28 to 38. This is how our Kids Cargo Trouser is sized: the number is the trouser's length, so it follows your child's height rather than the waist.
- Height in centimetres — 128, 140, 152. Usually imported stock. Here the number describes the child, not the trouser.
Our sizes, and the age each one usually suits
The Kids Cargo Trouser runs from 28 to 38, and every number is a length. Parents shop by age, so here is the age each length usually suits — and “usually” is doing real work in that sentence.
Take the age as a starting point and let the length decide. Children outgrow the length of a trouser long before anything else, which is exactly why we size on it. You can see all six lengths and eight colours on the Kids Cargo Trouser page.
- 28 — around 6 to 7 years
- 30 — around 8 to 9 years
- 32 — around 10 to 11 years
- 34 — around 12 to 13 years
- 36 — around 14 to 15 years
- 38 — around 16 years
Measure in two minutes, without chasing anyone around the room
The easiest measurement is not taken on your child at all. Find a trouser that fits them well right now, lay it flat on the floor, smooth the creases out and take a tape to it. Two minutes, no negotiation.
If the trouser you measured falls between two of our numbers, take the longer one. And if you are still unsure, send us your child's age, height and that length on WhatsApp — we will tell you which size to book before you order anything.
- Length: from the top of the waistband straight down to the hem, along the outer edge. That is the number to match against 28 to 38.
- Waist: measure straight across the flat waistband and double it.
- Inside leg: crotch seam to hem — worth knowing if you plan to turn a hem up.
- Prefer to measure the child? Waist over a shirt rather than a jumper, tape snug and level, then height barefoot against a wall.
Same age, different children
Age charts describe an average child who does not exist. In one classroom of ten-year-olds you will find a head of height between the tallest and the shortest, and both of them need trousers. So look at how your own child is built rather than arguing with the chart.
There is one temptation worth naming: buying two sizes up so it lasts two years. It rarely works out. A hem that drags gets stepped on, frays and goes grey at the back long before the child grows into it. One size of headroom is sensible; two is a year of tripping.
- Tall for their age — take the next length up.
- Short or slight for their age — stay on the smaller length; a trailing hem is the first thing to wear out.
- Mid growth spurt — the longer size, turned up once, buys you a season.
- Between two lengths — always the longer one. Cotton does not grow; children do.
School trousers and everyday trousers are not sized the same way
Uniform trousers are usually sold by waist and held up by a belt, because a school cares that they stay up and match. Everyday trousers — cargos, joggers, casual cotton — are bought for length and comfort, and worn until they are outgrown rather than until term ends. Comparing a uniform 24 with a cargo 32 is comparing a waist with a length; the two numbers have nothing to say to each other.
So before ordering from any shop, ours included, ask one question: is that number a waist, a length, or an age? Any seller who knows their product can answer it in a sentence.
Where kids' sizing goes wrong online
Most size complaints are not really about the chart. They come from ordering on an assumption, or from what happens in the first wash. Pure cotton is honest fabric, but it does not forgive a hot wash or a hot dryer — our washing guide covers the settings that protect the length you paid for.
- Ordering by age alone, from a brand whose chart you have never opened.
- Assuming two brands' “32” are the same trouser.
- Forgetting the wash — a length that was exactly right becomes exactly short.
- Not checking the exchange window before ordering. A size mistake is only a problem if you cannot swap it.
- Ordering mid growth spurt without allowing any length at all.
When the parcel arrives
Try the trouser on before anything else, and certainly before it goes near water. Washing is the one step you cannot undo — every seller's exchange, ours included, needs the garment unworn with its tags on.
If this is your first cash-on-delivery order, how cash on delivery works walks through the confirmation call, the rider and what you can check at your door.
- Have your child stand barefoot and straight — the hem should sit at the ankle, not on the floor.
- Check it with the tags still attached, and keep them on until you are sure.
- If the length is off, message us within 7 days for a free exchange, unworn with tags on.
- Pay at the door — cash on delivery, no advance, free delivery anywhere in Pakistan.
