A larger tablet is not the only way to make a reading session easier. The document, application layout and way you hold the device can each be part of the problem. Before shopping, identify what makes you stop reading: tiny text, repeated zooming, glare in a particular position or the effort of holding the screen.
Try a chapter or document you actually read, not a short demonstration page. A novel, scanned textbook and wide spreadsheet place different demands on the display. A change that helps one may do little for another.
Separate text size from page size
Check what the reading application lets you change. Where text can reflow, experimenting with font size, line spacing and margins may make better use of the screen. A fixed-layout document can behave differently: enlarging part of the page may require panning or a different view.
Use the same difficult page while comparing settings. Otherwise, a simpler paragraph can make one arrangement seem better when the actual difference is the material. Keep a note of a setting you like so you can return to it after experimenting.
Portrait and landscape views are worth trying for different documents. The useful orientation is the one that reduces interruptions for that particular material. It need not be the same for a novel and a diagram-heavy manual.
Change where the screen sits
Put the tablet on a suitable stand and see whether taking its weight out of your hands changes the session. Adjust the position within the stand's intended range. Check that the viewing angle works without covering a lamp or leaning over the desk.
Look at reflections in the place you read. Moving the tablet or the light can be more informative than buying a screen accessory immediately. If you consider a matte protector, investigate its fit and the trade-offs described for the product rather than expecting it to improve every type of image.
After a few sessions, decide which obstacle remains. If the document still needs constant panning at a readable size, a larger display may address a real limitation. If the main improvement came from a stand or application setting, keep that finding in the purchase decision. Buy more screen area for the task it solves, not simply because a small tablet felt inconvenient in one untested arrangement.
