🎒 How to Size & Fit Your Toddler’s Backpack

Bringing quiet luxury to kids backpacks. A guide from

As your toddler becomes more independent and starts carrying their own backpack, a good fit is key. A properly sized backpack helps support healthy posture, avoids discomfort, and lets them enjoy their daily adventures with ease.

Here’s how to make sure your little one’s backpack fits just right.

✅ 1. Choose the Right Size

Quick guide: The backpack should not be wider than your child’s back or hang more than 5 cm below their waist.

1–2 yrs

23–28 cm

5+ yrs

33–38 cm

8–10 litres

🧵 All That’s My Backpack bags are designed for toddlers – large sized to fit everything your child needs for daycare. A large backpack should be carried by a grownup until your child is 5.

🎒 2. Adjust the Straps

Your child should wear both shoulder straps so the backpack sits high and close to the back — ideally just below the shoulder blades and not drooping.

Strap Fit Checklist:

  • Sits above the bottom
  • Shoulder straps lie flat, not too tight
  • Base of the backpack rests in the curve of their lower back

🛠 Pro tip: Kids grow quickly – check and adjust the straps every couple of months.

📦 3. Keep It Light

Even a well-fitted backpack can cause strain if it’s overloaded.

General rule: The backpack should weigh no more than 10% of your child’s body weight.

For a 20 kg child, their backpack should weigh no more than 2kg, including everything inside.

💡 Packing Tips:

  • Stick to essentials (snack, water bottle, toy, jumper)
  • Distribute weight evenly inside
  • Use lightweight lunchboxes and containers

🚶 4. Watch How They Move

Once they’ve got the backpack on, have your child:

  • Walk a few steps
  • Raise their arms
  • Bend over

✔️ The backpack should stay put — not bounce or shift.
✘ If they lean forward or it slips off, try adjusting the fit or lightening the load.

📏 5. Check Regularly As They Grow

Growth spurts come fast! Check the fit every couple of months:

  • Are the straps too tight?
  • Is it sitting too high or low?
  • Are they ready for a bigger size?

Upgrading at the right time keeps things comfy and safe.
