Backpack size and buyer’s guide (by age and use)

Fit beats volume every single time. A good backpack sits above the hips, hugs the back, and feels balanced when the stairs appear. Bigger looks helpful, but the right liters with smart pockets will carry more with less effort.

Start with the daily load. Books or a device, lunch kit, bottle, and a light layer. If a laptop is a must, check sleeve size in inches. Two bottle pockets help in Dubai heat, because water goes on the outside and the inside stays dry and tidy.

Try the fit check at home. Pack a realistic day, put the bag on, and adjust the straps so the weight stays close. Walk a few steps, climb a short flight, then clip the chest strap if you have one. No wobble, no neck pull, no slipping straps.

Choose your carry persona

The Sprinter: Light timetable, loves moving fast. Look for a compact bag that hugs the back, breathable panel, and one big easy-access pocket.
The Librarian: Brings half the classroom home. Go structured back panel, firm base, wide opening, and strong zips that glide under load.
The All-Rounder: Books + PE twice a week. Prioritize balanced pockets, a snug laptop sleeve (even if not daily), and two bottle pockets for real hydration.
The Techie: Device rides along often. Pick a bag with a true 13/14/15" sleeve (listed in inches), cable pouch, and a soft, scratch-safe interior.

Trolley or backpack depends on the route. Trolleys help with long corridors and heavy books. backpacks win on buses and stairs. If you take many steps each day, hands-free is safer and faster. Reflective trim also earns its keep on early buses.
