Whether you’re browsing on-trend bags for fashion-conscious teens or durable school backpacks for elementary and preschool students, these tips and tricks are sure to steer you in the right direction.


Essential Factors for Choosing Kids’ Backpacks

Size and Fit Guidelines

The golden rule for how to choose the right back-to-school backpack is proper sizing. A backpack should never be wider than your torso or hang more than 10 centimetres below the waist. For younger children, try browsing for packs with about 10-15 litre capacity, while most teens and pre-teens can handle about 20-30 litres comfortably. Weight distribution also matters significantly. The Canadian Chiropractic Association recommends that a loaded backpack weigh no more than 10-15% of your body weight. For example, this means a 25-kilogram child should carry no more than 2.5-3.75 kilograms total.

Comfort and Ergonomic Features

Durable Design

Kids are notoriously tough on their belongings. Choose backpacks made from high-quality materials like ripstop nylon, eco-friendly recycled textiles or tough woven canvas. Water-resistant materials protect electronics and papers from snow or unexpected rain showers, a particularly important for Canadian weather conditions. Reflective strips help kids stay seen during darker winter months, while compression straps help maintain the pack’s shape when not fully loaded.

Expert Tips for Parents

Proper Fitting Techniques

Always have your child try on backpacks before purchasing. The pack should sit close to their back with the top not extending above their shoulders. Shoulder straps should be adjusted so the pack sits centered on their back, not pulling them backward. Check that your child can put on and remove the backpack independently. If they struggle with weight or fit, consider a smaller size or look for additional comfort features.

Smart Packing Strategies

Teach your child to pack heavier items closest to their back. This positioning improves balance and reduces strain. Use all compartments to distribute weight evenly rather than stuffing everything into the main section. Regular “backpack cleanouts” prevent unnecessary weight accumulation. Remove items that aren’t needed daily and consider leaving textbooks at school when possible.

Maintenance and Care

Extend your backpack’s life with proper care. Empty and air out the pack weekly, spot clean stains and always follow manufacturer washing instructions. It’s also a great idea to store backpacks in a dry place during summer months to prevent mould and mildew. Inspect zippers, straps and seams regularly for signs of wear, and repair or replace whenever necessary.


Making the Right Choice for Your Child

Selecting the best backpack involves balancing brand and style preferences with practical requirements like comfort and support. Consider their daily activities, school requirements and personal style when making your decision. Quality backpacks are truly an investment in your child’s comfort and health. While premium options may cost more initially, their durability and superior features often provide better long-term value.
