Laptop Size Calculator
The same inch count differs by ratio: modern laptops are mostly 16:10 (taller), while gaming and older models use 16:9. For bag fit, use the chassis dimensions from the spec sheet — usually 0.5–1 inch wider than the screen.
FAQ
How big is a 15.6 inch laptop screen?
At 16:9 it measures about 13.6 × 7.6 inches (34.5 × 19.4 cm). The chassis is usually around 14.1 inches wide, fitting most 15-inch sleeves.
What is the difference between 16:10 and 16:9?
16:10 is taller at the same diagonal — better for documents and web — and is now the mainstream. 16:9 matches video content and remains common in gaming laptops.
Can I pick a bag by screen size alone?
No. Chassis width varies by bezel design, so compare the laptop's physical W×D×H from the spec sheet with the bag's internal dimensions.
