Choosing a 15.6-inch Laptop Backpack: Practical Buying Tips for School, Work and Travel

A 15.6-inch laptop backpack needs to do more than just hold your laptop. In the UK, your bag has to cope with rain, crowded trains, bike rides and daily wear and tear. At the same time, you want room for books, a charger, lunch and personal items without the backpack becoming uncomfortably heavy.

However, the product name doesn't always tell the full story. So look out for these common pitfalls before you order.

Three Pitfalls When Buying a Laptop Backpack

1. Confusing "Water-Repellent" with Waterproof

A water-repellent laptop backpack can help keep out light rain or splashes. That doesn't automatically mean the bag is suitable for prolonged, heavy rain. Check whether the product information mentions water-repellent, splash-proof or fully waterproof.

What's more, a laptop compartment with a zip isn't automatically moisture-resistant. If you're facing heavy rain, consider using a separate rain cover and don't carry electronics outside in wet conditions for long periods.

2. Only Looking at the Inch Size

A backpack for a 15.6-inch laptop doesn't guarantee a perfect fit for every model of that size. Laptops vary in thickness, bezel size and casing. So, alongside the screen size, also check your laptop's dimensions and the size of the laptop compartment.

Watch out for conflicting information. The NINETYGO College-Style Dual-Shoulder Backpack states support up to 15.6 inches in its name, while the included product information mentions compatibility up to 14 inches. If you're considering this backpack for a 15.6-inch laptop, it's wise to check the current product specifications and dimensions before you buy.

3. Assuming Lots of Pockets Means Good Organisation

A laptop backpack with multiple pockets can be handy, but too many small compartments can sometimes make it tricky to store larger items. Focus on the combination of:

  • a separate, padded laptop compartment;
  • a spacious main compartment for books or clothes;
  • a pocket for your charger and cables;
  • a quick-access front pocket;
  • side pockets large enough for a water bottle or umbrella.

For commuting, a business laptop backpack with well-organised pockets is often more practical than a bag with lots of narrow zip pockets.

Key Specifications for Daily Use

Laptop Compatibility and Protection

First, check the maximum laptop size. A well-fitting compartment stops your laptop from moving around too much when you're walking. A soft lining or foam edge offers extra protection against light bumps, but a laptop backpack isn't a guarantee against damage from drops.

According to the product information, the Dell CP3724 supports laptops up to 16 inches and has a 360° foam cushion around the laptop compartment. This means the bag could also suit users who want a slightly roomier compartment than strictly necessary for a 15.6-inch model.

Capacity and Dimensions

A spacious laptop backpack is useful for students, pupils and commuters who carry several items every day. Capacity is usually given in litres. For a laptop, documents and accessories, a compact bag is often enough. For clothes, lunch or sports kit, more capacity is more practical.

The HP Travel has a capacity of 25 litres and, according to the product information, can be expanded to 30 litres. Its stated dimensions are roughly 32 × 24.5 × 44 cm. That makes this model interesting as a travel backpack with a laptop compartment, but always check whether the size suits your luggage and mode of transport.

Material, Comfort and Weight

A lightweight laptop backpack reduces the base weight, but comfort also depends on the shoulder straps, back panel and weight distribution. Look for adjustable straps, a chest strap on larger models and a carry handle for short distances.

According to the product information, the NINETYGO backpack uses 900D tear-resistant fabric, a material designed to withstand daily use. The bag also has a soft carry handle, anti-slip straps and reinforced side pockets. The stated water-repellent finish is not full waterproofing.

Frequently Asked Questions About a 15.6-Inch Laptop Backpack

Will every 15.6-inch laptop fit in a 15.6-inch laptop backpack?

No, not always. The inch size refers to the screen diagonal, not the full external dimensions of the laptop. So measure the width, depth and thickness of your device and compare them with the dimensions of the laptop compartment.

How long does a laptop backpack typically last?

The lifespan depends on the weight, how often you carry it, the zips, seams and exposure to rain. A sturdy fabric like 900D can be suitable for regular use, but overloading will shorten its life. Distribute the weight and follow the care instructions, such as cleaning with a damp cloth and air drying.

Is a water-repellent laptop backpack enough for cycling in the rain?

For short trips in light rain, water-repellent material can help. For prolonged or heavy rain, additional protection is advisable. A water-repellent laptop backpack is not automatically waterproof, so keep your laptop, charger and documents as dry as possible.
