Facebook cover photo maker

Which number this Facebook cover photo maker keeps

Facebook’s help page for Page covers gives three figures, and they describe different things. Two are container ratios: 16:9 when the cover is shown on a computer, 2.4:1 when it is shown on a phone, both left-aligned and bleeding to the edges. The third is a remark about loading speed, naming an sRGB JPG of 851 by 315 under a hundred kilobytes as the quickest to fetch. All three were read on September 7, 2026.

851 by 315 is 2.70:1, which is not 16:9 and not 2.4:1. It is advice about bytes that has spent a decade being copied as advice about shape, and it is why so many covers arrive with the right-hand end missing on a laptop. Everything downloaded from this page is 1600 by 900, or that doubled: the ratio is Facebook’s, the pixel count is ours, and there is no free canvas because the moment one exists the page can no longer promise a shape at all.

Seeing what the phone takes away

Given two published containers, the sane one to draw on is the taller. Occupying the desktop frame completely takes 16:9 and nothing else. Handed on to the 2.4:1 phone frame, that same picture keeps every pixel of its width and surrenders a strip along the top and another along the bottom — the trim anybody already anticipates from a banner. Reverse the two and the arithmetic runs out: there is nothing painted in the region the taller frame demands, so either pixels get invented or the artwork is shoved past its own edges.

The phone overlay is on from the start, so that band is outlined on the canvas while you work. Two things about it are worth stating plainly. It is calculated from Facebook’s 2.4:1, not copied from any rectangle Facebook has drawn. And because they never say which end of the height is sacrificed, it is centered here — a guess, made visible, rather than a claim.

The margin is yours to place

Rival editors print a tidy outline and call it the safe area. Facebook has issued no such thing. Everything they write on the subject is qualitative: a portrait sits over the left end, screens of different widths may trim and rescale what you upload, and on a handset the portrait laps roughly forty pixels of it. The last of those reads like a coordinate until you notice two things — the hedge in front of it, and that it measures a rendered layout on a device rather than any position inside your artwork.

So the dotted rectangle here begins switched off, sits wherever you drag it, and exists on glass only — the encoder receives your picture and your lettering and never learns it was there. Practically, keep anything that must be read out of the lower left, where the portrait lands, and out of the top and bottom strips the phone ratio removes. The published figures, each with the day it was checked, are gathered in Facebook cover photo size.

Personal profiles, and the weight advice

For a personal profile rather than a Page, Facebook prints exactly one rule, and it concerns width alone: seven hundred and twenty pixels, minimum. That article names no height, no proportion and no weight. Anything leaving here starts at 1600 across, so the rule is met several times over, and 16:9 stays the only cover proportion the company has put in writing anywhere.

PNG is the default for a cover built on a plain color, because Facebook themselves suggest it for covers carrying a logo or text. Add a photograph and the format switches to JPEG, which is normally far lighter for a photo; the other choice stays one selection away. When a download passes 100 kilobytes the receipt mentions Facebook’s loading-speed sentence and says outright that it is advice rather than a limit — nothing is refused and Facebook re-encodes the upload regardless. To aim at a byte target deliberately, compress image searches for the quality that lands under a figure you name while every pixel dimension stays put.

What is not here

No template gallery, no stock library, no account. There is also no profile-picture mode: Facebook stores that one square at 320 by 320 and draws a circle over it, which is a different job that square image already does properly. Nor is there a switcher between cover types, because the choice between shapes is the only decision on this page worth making and a menu would hide it.

For artwork that already exists, the image resizer crops and scales in one pass to numbers you type, and image dimensions reports what a file measures both as stored and as displayed — two answers that differ for anything shot on a rotated phone. Building the equivalent banner for a different network, the LinkedIn banner maker works to that platform’s own published figure instead.

Nothing you open is transmitted anywhere. Reading the file, compositing the frame and writing the finished bytes are all steps your own browser performs, and creatorvalet.com has no route that accepts an image. Test it rather than trust it: keep the network panel open while you build one, or see how to verify local processing.
