MobileRead Forums - View Single Post - A5-sized PDF device with buttons

Yapyap · 08-27-2026, 08:35 AM

I have to admit I got a little confused here by the initial ask .. Isn’t A5 size basically closest to 10’’ as e-readers go? So essentially twice the size of 7’’?

I checked with the size tool at https://comparisontabl.es/size-comparison/ and it looks like an A5 sheet of paper is essentially exactly the height of the screen of e.g. Boox Go 10.3 while being just a little narrower. The screen of the PocketBook Inkpad 4 is considerably smaller both in height and width, and a 7’’ Boox Go 7 is smaller still.

Top row is a 7’’ Boox Go 7, 7.8’’ PocketBook Inkpad 4, A5 paper and Boox Go 10.3 lined up, bottom row is each e-reader with the A5 paper. At least it helps me visualise this better.

10’’ e-ink devices with buttons are harder to come by though, but 7’’ is really much smaller than A5… newer Android ones are somewhat better for zooming than dedicated e-reader with less processing power, but I can’t see how one could zoom without the touchscreen being on. I suppose with cropping, if the original PDF has generous margins to crop away, and excellent eyesight (and if the PDFs have sharp, clear, not too small text) it might work for some people? (Not me, I’ve tried and .. nope. But my eyes suck.)
