Frequently Asked Questions

What is the best tablet size for students?
10–11 inches is ideal for notes, reading, and multitasking. It provides enough screen real estate for split-screen apps without being too bulky to carry.
Is 7-inch tablet too small?
It’s perfect for travel and reading but limited for heavy productivity. If you plan to do a lot of typing or drawing, you might find it cramped.
Which aspect ratio is better?
4:3 is better for reading and drawing as it mimics the proportions of a sheet of paper. 16:10 is ideal for movies and multitasking as it provides more horizontal space.
Does higher resolution require bigger screen?
Not necessarily, but larger screens benefit more from 2K or 4K resolution to maintain high pixel density and clarity.
