How to Buy Kids' Clothes as a Gift Without Knowing the Size

Not knowing a child's exact size should not stop you from buying them clothes as a gift. Use their age as a reliable fallback, size up rather than down when in doubt, and lean on a generous exchange window as your safety net if the fit turns out wrong once the gift is opened.

Start With Age, Not Guesswork

The good news is that you rarely need an exact measurement to buy children's clothes as a gift. Most kidswear, including the Dinooz range, is sized primarily by age band, from newborn through to 10 years, which means age alone gets you most of the way to the right size. If you know roughly how old the child is, or is about to turn, you already have the main piece of information you need.

Where people go wrong is overthinking it. You do not need the child's height in centimetres or their exact weight. A simple "she just turned 2" or "he's about to start Year 1" is usually enough to land in the right size band.

Sizing-by-Age Fallback: What Usually Works

As a general rule, most children fall somewhere close to the standard age based size for their age, though there is always some natural spread. If you know the child's age but nothing else, ordering the size that matches their current age, or the age they are about to turn, is a sensible default. The size guide breaks this down clearly with age ranges rather than just numbers, which is far easier to work from than a measurement chart if you have not seen the child recently. Our piece on measuring a child's size at home is useful too if you happen to have a moment with the child before buying.

When in Doubt, Size Up

If you are torn between two sizes, or you suspect the child might be tall or big for their age, the safer choice is almost always to size up rather than down. A slightly large outfit still gets worn, whether that means rolling the sleeves for a few weeks or simply growing into it a little later. A slightly small outfit, on the other hand, often cannot be worn at all, which means the gift goes to waste. In the UAE's climate, a slightly loose fit in breathable cotton is also more comfortable in the heat than something tight, so sizing up rarely costs you anything.

Your Safety Net: Easy Exchanges Within 14 Days

Even with the best guesswork, sometimes a size is simply wrong, and that is fine. Returns and exchanges are accepted within 14 days of delivery, free of charge, so a gift you were unsure about is never a locked in risk. If the outfit turns out to be too big, too small, or simply not quite right, it can be exchanged for a different size without hassle, either by the person who received it or by you if you would rather sort it out yourself. Details are on the returns page.

This is worth mentioning to the recipient too, especially if they might feel awkward about a gift not fitting. A simple "if it doesn't fit, it's easy to exchange, no pressure" takes the stress out of it for everyone.

A Few Extra Clues If You Have Them

If you happen to know a little more, use it. A recent photo where the child's clothing looks snug or loose against their frame, a comment from the parents like "he's tall for his age," or knowing the size of an older sibling at the same age can all nudge your decision. None of these are essential, but they help you decide between two adjacent sizes if you are stuck between, say, 2-3 years and 3-4 years. If you are buying for a child you rarely see, our guide to buying kids' clothes online covers more of these everyday shopping questions.

It also helps to remember that fit matters less for a gift than it does for everyday school or daycare wear. A soft, stretchy set has some natural give built in, so it tends to forgive a slightly imprecise guess far better than something structured or fitted would. Choosing softer, more flexible styles when you are unsure of the exact size is a simple way to reduce your risk without needing any more information about the child.

Explore sizes from newborn to 10 years at the shop, and rest easy knowing any size mismatch is a simple, free exchange within 14 days. If budget is front of mind, see our gifts under AED 100 picks.
