Getting the right fit is the single most important factor when buying school shoes. Ill-fitting shoes can cause blisters, discomfort, and even long-term foot problems as your child grows. The good news is that measuring children's feet at home is straightforward once you know the proper technique. In this guide, we walk you through everything you need to know so you can confidently find the perfect pair — and our school shoe size guides make converting your measurements into the right size even easier.
Why Measuring at Home Matters
Children's feet grow surprisingly fast. Between the ages of 4 and 6, feet can grow by a full shoe size every three to four months, and even teenagers experience growth spurts that catch parents off guard. Relying on the size printed inside a pair of old shoes is unreliable because sizing varies between brands and styles. A UK size 2 in one brand may fit quite differently in another.
Measuring at home gives you an accurate, up-to-date starting point before you shop. It also saves time — rather than trying on dozens of pairs in-store, you can narrow down the right size range in advance and shop with confidence, whether you are browsing boys school shoes or girls school shoes.
What You Will Need
You do not need any special equipment. Gather these items before you start:
- Two sheets of A4 paper (one for each foot)
- A pen or pencil
- A ruler or tape measure marked in centimetres
- A hard, flat surface such as a tiled or wooden floor
Avoid measuring on carpet, as it can shift the paper and give an inaccurate reading. Have your child wear the type of socks they would normally wear to school — this ensures the measurement reflects real-world conditions.
Step-by-Step: How to Measure Your Child's Feet
Step 1 — Stand on the paper. Place the sheet of paper on a hard floor against a wall. Ask your child to stand on the paper with their heel touching the wall. Make sure they are standing upright with their weight evenly distributed — sitting or tiptoeing will give an inaccurate reading.
Step 2 — Mark the longest toe. Using your pen, draw a small line at the very tip of their longest toe. For most children this is the big toe, but some children have a longer second toe, so check carefully.
Step 3 — Measure the length. Remove the paper and use your ruler to measure the distance from the edge of the paper (the wall line) to your pencil mark. Record this measurement in centimetres.
Step 4 — Measure the other foot. Repeat the process for the other foot. It is completely normal for one foot to be slightly larger than the other — always use the larger measurement when selecting a shoe size.
Step 5 — Add growing room. Add approximately 1 to 1.5 centimetres to the longer measurement. This gives your child room to grow without the shoes feeling too loose on day one. This growing room is especially important for school shoes that need to last a full term or longer.
Step 6 — Convert to a shoe size. Use our brand-specific size guides to convert your centimetre measurement into the correct UK shoe size. Each brand has slightly different sizing, so always check the guide for the specific shoes you are considering.
Measuring Width: The Often-Forgotten Step
Length is only half the equation. Width matters just as much for comfort and healthy foot development. To measure width, wrap your tape measure around the widest part of your child's foot — usually across the ball of the foot just below the toes. Record this measurement in centimetres.
Most school shoe brands offer standard and wide fittings. If your child's foot measures wider than average, look for shoes specifically designed for wider feet. Brands like Hush Puppies and Kickers are known for offering generous and comfortable fits that accommodate a range of foot widths.
Top Tips for an Accurate Measurement
Timing makes a difference. Feet swell slightly throughout the day, so measure in the afternoon or evening when feet are at their largest. This ensures the shoes will be comfortable even at the end of a long school day.
Always measure both feet. As mentioned, one foot is often slightly larger, and buying for the smaller foot is a common mistake that leads to pinched toes and discomfort. Re-measure every six to eight weeks during the school year, especially for younger children and teenagers going through growth spurts.
When in doubt between two sizes, go up rather than down. A shoe that is slightly roomy can be managed with thicker socks or an insole, whereas a shoe that is too small will cause pain and may need replacing sooner.
Choosing the Right School Shoes After Measuring
Once you have your child's measurements, the next step is finding a shoe that combines the right fit with durability and style. Look for reinforced toes and sturdy soles that can handle playground wear, breathable linings for all-day comfort, and fastenings your child can manage independently — whether that is lace-up, touch fasten, or slip-on.
Quality brands invest in proper foot support and use materials that mould to your child's foot over time. Browse our full range of top school shoe brands to find the perfect pair now that you know exactly what size to order. With the right measurements in hand, you can shop confidently knowing your child's feet are well looked after.
