What size backpacks do kids need for school?

Before you know it, your little one will already be a big kid ready to go to school. Whilst there are many emotions that come with sending them off to school, worrying about their backs shouldn’t be one of them. Along with fresh pencils, colourful crayons, and new, cool lunch boxes, a new backpack, or at least a more lightweight kids’ backpack might be in order too! This guide will help you find the right backpack size for your kids!

Why is the size of a school bag important?

In general, kids’ backpacks should be no more than 10 to 15% of their body weight. If your child weighs 23kg, they should have a 3-5kg bag when full. The smaller your child, the smaller their bag should be.

There are many reasons why you should care about the size of your child’s school backpack. First, a bag that is too small might not be able to fit all of the school supplies the child needs, which can be frustrating for you and your kid. On the other hand, a school bag that is too big may be too heavy for the child to carry comfortably, which may result in back pain or other physical discomfort.

Your child’s posture and overall health may also be affected by the bag’s size. Muscle strain and other physical issues can result from improperly carrying a heavy bag on one shoulder. Kids’ backpacks must be worn with both straps in order to distribute weight properly. If not, they may experience neck and back pain as a result of having to unevenly adjust their hips and shoulders to accommodate the bag’s weight. Their spine can be compressed unnaturally if the school backpack is too heavy or worn incorrectly. An unsafe or heavy backpack can create long term issues with posture.

How to choose the right backpack for your child?

Choosing the right boys or girls school backpack can be an important decision to ensure their comfort, health, and safety. Here are some factors to consider when choosing a backpack for your child:


Consider the age, size, and needs of your child. A younger child may require a smaller backpack with a capacity of around 10-15 liters, while an older child may need a larger backpack with a capacity of around 20-30 liters.


Look for a backpack that fits your child’s body properly. The backpack should sit comfortably on the child’s back and not be too tight or too loose. The shoulder straps should be adjustable and padded for comfort, and the backpack should sit at the waist level.


Choose a backpack that is lightweight and does not add unnecessary weight to your child’s load. A backpack should weigh no more than 10-15% of a child’s body weight.


Look for cute backpacks with features that can help distribute weight, such as padded straps, and waist belts. Consider the number and size of pockets and compartments to ensure your child can organize their supplies easily.


Look for reflective materials or bright colors to help your child stay visible to drivers and other pedestrians. Cute backpacks from Spencil come in a variety of colours, styles, and designs to match your child’s mood and interest!

When choosing a backpack, consider the child’s size, the amount of school supplies they need to carry, and any other activities they may need the backpack for. It’s also important to look for a backpack with wide, padded shoulder straps and a padded back to help distribute the weight and reduce the risk of injury.

What size backpack do kindergarteners need?

Kindergarteners often need a smaller backpack than older kids do because of their smaller bodies and inability to carry as many supplies. A kindergartener often needs a backpack that holds between 10 and 15 litres, which normally has space for a small lunchbox, a change of clothes, and some school supplies.

It is essential to keep in mind that the backpack should not be too heavy for the child to carry comfortably and should fit the child properly. Look for a backpack with shoulder straps that can be adjusted to fit the child’s body snugly and are padded. Additionally, opt for a backpack with a padded back panel to assist with weight distribution and lessen the likelihood of injury.

Generally, while picking a backpack for a kindergartener, focus on solace, security, and usefulness over style or design.

What size backpack do primary school kids need?

Primary school kids, typically in grades 1-3, may require a backpack with a capacity of around 10-15 liters. This size is suitable for carrying a few textbooks, notebooks, pencils, and other small school supplies.

As with any backpack, it’s important to make sure the child can carry it comfortably and that the backpack fits them well. For optimal weight distribution and injury prevention, choose a backpack with padded back panels and adjustable, padded shoulder straps.

It’s also a good idea to choose a backpack with multiple compartments to help the child stay organized and easily access their supplies. This can help prevent overloading the backpack and causing unnecessary strain on the child’s back and shoulders.

Overall, when choosing a backpack for primary school kids, prioritize comfort, functionality, and safety over style or fashion.

What size backpack do high school kids need?

The size of a backpack for a high school student depends on their individual needs and the items they typically carry with them. However, a good rule of thumb is to choose a backpack that can comfortably accommodate their textbooks, notebooks, laptop or tablet, and other essential items.

A backpack with a capacity of 20-30 liters is usually a good choice for most high school students. This size should be large enough to carry their everyday items while still being comfortable to wear and not too bulky.  Make sure their bags have enough space, but are not larger than necessary. These backpacks are compact, but often have extra compartments to store a calculator, pens, and other stuff they need.

It’s also important to consider the quality and durability of the backpack. Look for a backpack with sturdy straps, a padded back panel, and a waterproof or water-resistant exterior to protect against the elements. Additionally, choosing a backpack with multiple compartments can help keep things organized and easy to access.
