TikTok Banner Maker: One Photo into Three Posts

How do I make a TikTok banner with 3 posts?

The maker at the top of this page does exactly that in a single pass; with a photograph in hand it is the shorter road, and the figures are baked in. Prefer to cut by hand, or want to know why the cut lands where it does? What follows is the manual route, with the arithmetic and the failure modes attached.

Which of the two are you building?

One label covers two unrelated objects, and merging them is the most frequent mistake across the tutorials reviewed for this site. It explains why someone following a make-a-banner guide ends up hunting through their phone for a menu that was never there.

One sentence worth an hour of your time: when the editor offers no background control, three ordinary posts give you a grid banner without needing one. The converse holds as well — with the background option available, a header is a single upload and this page becomes optional.

One page, one method. The native background — where the control lives and what to do without it — belongs to how to get the banner and the not-showing guide. Neither is restated here.

Canvas and seams

Begin with a single wide photograph, never three separate files. A shared canvas is what keeps the cells aligned; crop each one independently and a pixel or two of drift makes the seams jog. Two shortcuts exist before you cut anything: the free tiktok banner templates are already laid out for this grid, and the tiktok banner size page lists every frame the canvas must satisfy.

1. Set the canvas User report

   3240 × 1440 px covering three 1080 × 1440 cells: the convention shared by splitter tools and creator write-ups. It is not an official TikTok dimension, and no official figure exists for the native banner either. Read it as a working canvas.

2. Hold content away from the cell edges User report

   Keep faces, type and marks off the two third-lines and clear of every cell boundary. Each cell in the grid is flanked by unrelated posts, and the gap swallows anything touching its edge.

3. No gutters, borders or shadows Official

   Every seam in a finished banner is a gap the app supplies, not a line painted into the file. Bake in a border or a shadow and you get two seams where one belongs. The three-column layout is documented; the spacing comes with it.

4. With portrait sources, expect the middle band Unconfirmed

   Per community figures, a 1080 × 1920 portrait shows roughly its central 1080 × 1440 band inside a cell. Nobody has measured this per device, so run the preview yourself before posting three times.

Happy to let something else do the arithmetic? The maker above cuts one photograph into three 1080 × 1440 cells, marks the seams and names the files in posting order. Decoding happens in the tab; nothing is uploaded. The manual route stays exactly as described — any editor with a fixed-size crop achieves the same result and leaves you the original.

What the maker does, and does not

Hand-cut splits fail in two predictable ways: thirds that miss by a few pixels, and a posting order that runs backwards. The tool addresses those two things and nothing more.

• Everything happens in the tab. Drag, zoom, rotate, download. The file is read locally, so there is no upload step to take on trust.
• The filenames encode the order. 01 is the right third, 02 the centre, 03 the left; the ZIP also carries post-order.txt repeating it in words.
• The preview is a drawing. The profile view is built from scratch here, so no part of it passes itself off as the app.

Back to the maker, or read on for the manual route, the figures and the reason the order runs backwards.

Publish, then pin

The order trips people up because it runs backwards: in most builds the cell you post first lands on the right. So post in reverse — right, centre, left — and the picture resolves correctly once the third one is live.

1. Post the right cell first User report, then the centre, then the left. In most builds the newest post lands leftmost, hence the reversal.
2. Visit your profile after every post. If the arrangement differs from the preview, work out how your app orders posts before continuing; re-pinning can help, though behaviour varies.
3. Pin the three. Pinning keeps the row at the top once later posts arrive. Pinning itself is User report, not documentation, and whether a newer pin can push one out of the row is Unconfirmed.
4. Reload and read the row. Should the picture run backwards, re-pin in the sequence you want and inspect the result; pin behaviour varies by build.

Why not a single post? The grid banner is three posts by construction; the seams are the app's column gaps. One wide upload renders as a lone portrait cell, never a strip. No one-post variant of this method exists.

Four ways it breaks

Almost every broken grid banner in the material we reviewed failed in one of four ways. Each is visible in your own preview before a single stranger sees it:

One check catches all four: open your profile after the third post and before pinning. Every failure costs less to find there than in a stranger's comment.

Sizes, pinning, and that feature
