Pottery Barn Kids Backpack Size Comparison

Thank you Pottery Barn Kids for partnering with me for this post. 

This is our second year with Pottery Barn Backpacks. They are hands down my favorite, amazing quality and looks the same at the end of the year than they did the day I first bought it. And if I’m being completely honest, my kids are HARD on their backpacks. I mean they sit on it, and drag each other on it and pretend they’re Santa on a sleigh- They got in trouble for this one. But if you were like me last year, you may wonder which size is best for your child. I actually have returned backpacks because they were too big or too small.

It can get even a little more tricky especially when ordering backpacks online. You can look at the specs online but what’s super helpful is seeing it on your child, or another child who’s close in age with your own child. So in this post I’m going to share with you how all the different size backpacks look on my children.


Which size Pottery Barn Kids Backpack is right for your child?

Mini Backpack:

*For reference: Laila is 10 months old, weighing 20 pounds*

This is what we got for Laila. She is not going to school yet, but I volunteer frequently at the boys’ school so they have a nursery for babies, when moms are volunteering. So I got her this backpack to carry her diapers, wipes, blanket, and a couple toys!

We also had this size backpack for Joel when he was in the moms morning out program, however we returned it for a larger size because it didn’t fit his folder and lunch box. In his program they send home a take home folder and crafts, and I figured it would be easier to just get him a larger backpack that will hold all his school things, even though it was huge on him.

  • Fits children who are 36–42″ tall.
  • Overall: 8.5″ wide x 4″ deep x 10″ high
  • Interior: 8″ wide x 3.5″ deep x 9.5″ high
  • Exterior Pockets: 3
  • Exterior Front Panel Pocket: 6.5″ wide x 5.5″ high
  • Exterior Side Pocket (2): 4″ wide x 4″ high
  • Shoulder Strap (2): 2.5″ wide; 12−19.5″ long
  • Carrying Handle: 1″ wide x 6″ long

Small Backpack: 

*for reference, Elias is 43 inches tall and 38 pounds.

*Same backpack on Joel, he’s like 38 inches and weighs 32 pounds. A little big, but this is the size we need for him*

This is the size we upgraded Joel to when he was 2 years old, and what Elias used last year when he was 3. This is the PERFECT size for a preschooler, in my opinion. It holds all of their things-folder, lunch box, sweater, crafts, water bottle, and a random toy that they try to sneak into class.

  • Fits children who are 43–49″ tall.
  • Overall: 12″ wide x 6″ deep x 15″ high
  • Interior: 11.5″ wide x 5.5″ deep x 14.5″ high
  • Exterior Pockets: 3
  • Exterior Front Panel Pocket: 7.5″ wide x 8.5″ high
  • Exterior Side Pocket (2): 5.5″ wide x 5.5″ high
  • Interior Pockets: 1
  • Interior Pocket: 6″ wide x 4″ high
  • Shoulder Strap (2): 2.5″ wide x 16–30.5″ long
  • Carrying Handle: 1.5″ wide x 7.5″ long

Large Backpack:

This is the size we got for RJ last year for kindergarten and this year for Elias (now that he’s in VPK). I love this size for 4+ years old. We could’ve gotten away with the Small backpack for Elias this year, but the rate he’s growing we know this size backpack would look 100% normal mid-year, and even use next year when he enters kindergarten.

With RJ he’s able to fit his folder, planner, lunch box, sweater, library books, random crafts he made at school and more. This size backpack is going to give you the most space for your growing child.

  • Fits children who are over 48″ tall
  • Overall: 14″ wide x 7.5″ deep x 17″ high
  • Interior: 12.5″ wide x 6.5″ deep x 16.5″ high
  • Exterior Pockets: 3
  • Exterior Front Panel Pocket: 8.5″ wide x 8.5″ high
  • Exterior Side Pocket (2): 7″ wide x 7″ high
  • Interior Pockets: 1
  • Interior Pocket: 7.5″ wide x 5.5″ high
  • Shoulder Strap (2): 3″ wide x 18–34″ long
  • Carrying Handle: 1.5″ wide x 6.5″ long

So hopefully the pictures were super helpful, and you’re able to choose the perfect size for your child. Just remember you can return your backpack to Pottery Barn Kids If it’s not the right size. However, if it’s personalized-you can’t. That’s something to consider.

If you have a local Pottery Barn Kids near you, I’d recommend going there and trying the different size backpacks on your child! That’s what I wish I did the first time.
