What Size School Uniform Should I Buy?

Choosing school uniforms is hard enough — but when your child sits between sizes, it can feel like a parenting pop quiz you didn’t study for. Relax. You’re not alone, and there is a right answer (spoiler: it usually involves sizing up).

At Lowes Schoolwear, we help Australian families get the fit right every day. Here’s our simple, stress-free guide to choosing the best school uniform size when your child is between sizes.

Short Answer: Size Up (Most of the Time)

If your child falls between two uniform sizes, we generally recommend choosing the larger size.

Why?

• Kids grow fast (sometimes inconveniently fast)
• A bigger uniform lasts longer
• Comfort beats snug every single school day

A uniform that’s a little roomy in Term 1 is far better than one that’s too tight by Term 2.

When Sizing Up Is the Best Choice

Sizing up works especially well for:

• Shirts and polos – extra length prevents mid-year shrinkage surprises
• Jumpers and fleeces – relaxed fits still look neat
• Blazers – designed with structure and growth in mind
• Shorts and trousers – adjustable waists are your secret weapon

Lowes tip: Many of our trousers and shorts feature internal adjustable waistbands, making it easy to fine-tune the fit now and later.

When You Might Stay True to Size

There are a few exceptions where sizing up isn’t ideal:

• Skirts and dresses – too much length can affect comfort and movement
• Slim-fit styles – oversized can look boxy
• Younger children – excessive fabric can be distracting (and trip-worthy)

If your child is unlikely to grow significantly during the year, choosing the closer size may make sense.

Check These Fit Areas Before You Decide

When trying on school uniforms, focus on these key spots:

• Shoulders: Seams should sit neatly without pulling
• Waist: Snug but comfortable when sitting
• Length: Sleeves and hems should allow movement without dragging
• Chest: No tightness when arms are raised

Have your child sit, bend, stretch, and give the uniform a proper test drive.

Use the Lowes Size Charts (They Matter!)

Not all uniforms fit the same. At Lowes Schoolwear, each product includes a detailed size chart designed for Australian school standards.

Always:

• Measure your child first
• Match measurements to the chart — not just age
• Use height as your primary guide when between sizes
