Buying Guide
How to Buy a Laptop Bag
This short guide explains what to check when buying a laptop bag so you can pick the right type, size and features quickly. It covers the main factors to consider, the common styles available, the key specifications to prioritise and practical buying tips.
Key factors to consider
Size and fit: always measure your laptop across its widest, deepest and thickest points and compare with the bag's internal sleeve size. Many bags list compatibility for 15.6 to 17.3 inch laptops so check exact measurements rather than just the quoted inch size.
- Protection level: look for a padded laptop sleeve (0.5 cm foam offers basic protection) and internal dividers to prevent items colliding.
- Material and water resistance: polyester, nylon or oxford fabric resist light rain but zippers are often not waterproof, so expect only splash resistance.
- Comfort and carry options: padded shoulder straps, breathable back panels and removable straps make daily use easier.
- Travel convenience: a luggage/trolley strap and TSA-friendly opening save time at airports.
Types and who they suit
- Backpack: best for commuters, students or travellers who carry heavier loads. Backpacks often offer anti-theft features, breathable mesh backs and larger capacity.
- Briefcase / messenger: ideal for office workers wanting a professional look and easy access. Many are slim and have organised organisers for pens and documents.
- Messenger / crossbody: good for light loads and quick access. Choose one with a detachable strap if you want flexibility.
- Expandable bags: useful if you sometimes carry extra items; expansion zippers can increase width by a couple of inches for clothes or books.
Important features and specifications to check
Practical checklist before you buy:
- Internal sleeve dimensions and laptop compatibility, not just the stated inch size.
- Number of compartments and organiser pockets for charger, mouse, phone and documents.
- Padding thickness and type: denser foam and separate laptop compartments give better shock protection.
- Security: hidden rear pockets, combination locks or double metal zippers add theft protection.
- External features: USB charging port and headphone jack are handy but need a power bank to work.
- Build details: reinforced stitching at stress points, metal zippers and a sturdy handle increase lifespan.
- Weight and overall dimensions: lighter bags reduce strain but may offer less protection; check listed weight if you plan long commutes.
Where to buy, common mistakes and expert tips
Online versus in-store:
- Buy online for more choice and often better prices, but read size specs, user photos and recent reviews carefully.
- Try in-store if you want to test fit, feel materials and assess comfort in person.
- Buying by stated laptop inch only without checking internal sleeve dimensions.
- Assuming "waterproof" when only the fabric is water resistant; zippers and seams often leak in heavy rain.
- Ignoring strap comfort and back padding because poor fit quickly becomes annoying.
- Overpaying for unnecessary features you will not use.
- Measure your laptop and chargers first, then check internal measurements on the product page.
- If you travel, prefer a bag with a luggage strap and a wide opening for security checks.
- Choose a bag with removable straps for versatility between briefcase and shoulder carry.
- For anti-theft, use hidden pockets and a simple combination lock, but read setup instructions before use.
- Expect good everyday laptop bags under £30; spend more only for premium materials or extra protection.
