Gray Bars Around Your Planner? It Is a Page Size Problem.

You bought the planner. You sideloaded it. You opened it on your tablet, and there it is, floating in the middle of the screen with a band of empty gray down each side. Or it fills the width but the boxes are so short you cannot fit a normal sentence in them. Or the whole thing looks slightly soft, like a photo that was blown up too far.

Nothing is broken. The file is almost certainly fine. What you're seeing is a page-shape problem, and once you know how to spot it, it takes about five minutes to fix.

Your planner has a page size, and your screen has a shape

Every PDF page has a fixed size baked into the file. Most planners sold online are built at one of two standard paper sizes. US Letter is 8.5 by 11 inches, which makes a page about 1.29 times as tall as it is wide. A4 is 210 by 297 millimeters, noticeably narrower and taller, at about 1.41 times as tall as it is wide.

Your tablet screen has its own shape, and it is usually not either of those. The reMarkable 2 screen is 1404 by 1872 pixels, which is exactly 3:4, or 1.33 times as tall as it is wide. The reMarkable Paper Pro is a different pixel count but the same 3:4 shape. Smaller and narrower devices sit somewhere else entirely.

When a page shape and a screen shape do not match, the reader has to pick a compromise. It will either shrink the page until the whole thing fits and leave empty bands on two sides, or fill the screen and push part of the page out of view. Neither is a bug. It is just geometry.

The practical effect is what you actually feel. A Letter page on a 3:4 screen is close enough that you get thin gray strips. An A4 page on that same screen is a bigger mismatch, so the page shrinks more, the ruled lines get closer together, and suddenly your handwriting feels too big for the boxes. You have not gotten worse at writing. The lines moved.

How to check what size your planner actually is

You do not have to guess. The fastest way is on a computer, not the tablet.

• Open the PDF in any desktop reader and look for document properties, file info, or a similar menu item. There is a page size listed there, usually in inches or millimeters.
• If you are on a Mac, opening the file in Preview and checking the inspector shows the same thing.
• If you still have the product page or the listing you bought from, the page size or the intended device is often stated right in the description. That is worth reading before you buy, not after.

Write the number down. Once you know whether you are holding a Letter file, an A4 file, or something built to a device size, every other decision gets easier.

What your tablet's fit settings can and cannot do

Most e-ink readers give you some control over how a PDF sits on the screen. The options are usually some combination of fit to page, fit to width, and a manual zoom, sometimes with a way to trim the white margins automatically.

Fit to page shows you the whole page and accepts the empty bands. This is the right choice for a hyperlinked planner, because every navigation button stays visible and tappable. If you are annoyed by gray strips but your links all work, honestly, leave it alone. You stop noticing them within a day.

Fit to width or a manual zoom fills more of the screen and cuts off the top or bottom. On a planner this is usually a bad trade, because the navigation row that gets you back to the monthly view is often exactly what scrolls out of sight.

Auto margin trimming, where your device offers it, can genuinely help. It removes blank space around the edges rather than changing the page content, which gets you more usable area without distorting anything. Turn it on, flip through a few pages, and check that nothing you tap has moved.

What none of these settings can do is change the shape of the page. They only change which part of it you see. If the mismatch is large, you are choosing between two imperfect views rather than fixing the underlying file.

Cropping the file is a real fix with a real cost

You can crop a PDF on a computer to change the visible page area, and for a plain notebook or a lined refill this works well. Trim the dead margins, resync the file, and you get a page that sits closer to your screen shape.

For a hyperlinked planner, be more careful. Cropping changes where everything sits relative to the page edges, and depending on the tool you use, the tap targets may or may not end up where you expect. If you try it, keep the original file, crop a copy, and then test it properly. Tap through a month link, a week link, and a back button before you commit to the cropped version for the rest of the year.

If that sounds like more work than you want to do, that instinct is correct. Which brings us to the boring answer.

The easiest fix is buying the size you need

A planner built at your device's page size does not need cropping, does not letterbox, and puts the ruled lines at a height that matches how big you actually write. The writing space feels right because it was drawn to feel right on that screen, not scaled into it after the fact.

This is why our planners are listed by device rather than as one generic file. The undated hyperlinked planner for Kindle Scribe and reMarkable Paper Pro is sized for those screens and covers daily through annual pages, with a Monday or Sunday start. If you would rather start the new year on a dated file, the 2027 dated daily planner is built the same way, with monthly calendars, vertical weekly spreads, and daily pages.

If you own something smaller or an unusual size, look for files that ship more than one page size in the download. Our undated goal planner is drawn natively for the reMarkable Paper Pro Move and includes eight other page sizes in the same purchase, so you can load the one that matches whatever you are actually holding.

Before you buy any digital planner, check two things: the page size, and whether the seller says which device it was drawn for. Those two lines in a product description will save you more trouble than any zoom setting on your tablet.
