A backpack is an essential accessory for kindergarten students. This is where they will be packing all of their belongings for a day at school, so it needs to be the right size they can safely carry without compromising their back and shoulders. But what size do kindergarten students need in a backpack?

Kindergarten students need to fit their day’s essentials into one sturdy backpack. It should have a capacity of 20 to 28 liters, measuring 2 inches more than the distance from their shoulders to belly button and 2 inches longer than the distance between their shoulder blades.

These are general guidelines for helping you find the right size for a kindergarten student’s backpack. Continue reading for more helpful information below.

What Size Backpack for Kindergarten

Parents have a lot to think about when sending kids off to kindergarten. You always want to make sure that they have everything they need for the day packed safely into their backpacks while ensuring the pack is of the right size. Improperly sized backpacks can cause discomfort and even injury, which is why the correct size is important.


The ideal capacity for kindergarten backpacks ranges from 20 to 28 liters. This is adequate for packing their daily school essentials such as daily folder, snacks, lunch, school supplies, and other seasonal items without being too large or small.

The most important aspect you should keep in mind when it comes to determining the kindergarten backpack size for your child is that its total packed weight must never exceed 15% of their own bodyweight. Experts have determined that this capacity weight is ideal as well as safe: anything more can increase the risk of injury among kindergarten students especially in their shoulders and back.


The standard size for a kindergarten backpack is around 12 inches (L) by 7 inches (W).

However, there is no one-size fits-all dimension for kindergarten backpacks since kids of the same age will have different body types. Some kindergarten students may also need to pack more into their backpack than others.

It’s more important to use a backpack that is tailored to your child’s body type and their needs than to go with a standard size because at the end of the day, it should be comfortable and safe for them to use daily.

Measuring Your Child

To find out what dimensions a backpack for kindergarten should be, follow the step-by-step guide below. It will teach you how to measure your child and determine the right size pack based on these.

What You’ll Need

The only tool you will need is a measuring tape, which come in handy for measuring your child’s backpack needs based on their specific body type.

Follow these steps to get an accurate measurement for a backpack that’s best for your child:

  1. Measure the distance from the shoulders down to the belly button; add 2 inches to this length. This will determine the ideal length (height) of the backpack.
  2. Measure the distance from one end of your child’s shoulder blade to the other, from their back. Add 2 inches, and this is how wide the backpack should be.

Last but not least, also consider the height and size of your child’s belongings before you buy a kindergarten backpack for them. For example, notebooks and folders are around 12 inches in height, so the backpack should be at least 14 inches long.
