TikTok slideshow photos cropped or zoomed in: causes and fixes

Why do TikTok slideshow photos look cropped or zoomed in?

TikTok documents little here. As of November 2026, its Creator Academy photo-posting article (opens in a new tab) advises cropping all photos to the same ratio for a cleaner look. It gives no pixel size or aspect ratio for photo posts, and we found no TikTok page that describes how the app displays photos of different ratios.

So "mixed ratios get cropped" is plausible, but it is not a documented cause. The table separates what a source states from what is worth checking.

How do you tell a real crop from an overlay?

The two look alike on a phone and have different fixes.

1. Open the exported file on your computer, at full size. If a headline is cut off there, the cut is in your file, and no app setting will fix it.
2. Open the post on your phone and screenshot the same slide.
3. Compare the two. If the screenshot shows less of the picture along the edges, the platform cropped it. If the picture is whole but the text is covered at the bottom or right, an overlay sits on top of it. That second case is a layout problem, covered in text cut off on slides.

How do you pre-crop a mixed set to one ratio?

Choose one ratio for the whole post, then crop every photo to it before you upload. The table shows how much of each common source survives. The numbers are our own arithmetic, for a crop centered on the picture.

Two lessons come out of the table. A landscape photo cropped to 9:16 keeps under half of its width, so the subject has to sit in the middle. And a wide screenshot keeps about a third, so cropping it usually destroys it. For those, do not fill the frame. Fit it.

Should you fit or fill?

Fill crops the photo until it covers the whole slide. Fit shrinks the photo until all of it shows and fills the rest of the slide with a color or a blurred copy you make yourself. You then control what appears, and TikTok has nothing to crop.

On a 1080 x 1920 canvas, a 4:3 landscape photo fitted to the full width is 1080 x 810, which leaves 1,110 px to fill: 555 above and 555 below. A 16:9 screenshot fits at 1080 x 608, leaving 1,312 px. Use fit for screenshots, charts and photos where an edge matters. Use fill for photos with a clear center.

What is a safe layout once every slide has one ratio?

• Subject in the middle band. Faces and key objects away from all four edges.
• Text inside a cautious box. The TikTok safe zone page derives a strict box of x 150 to 880 and y 270 to 1250 on a 1080 x 1920 slide. Those are rule-of-thumb numbers from conflicting community guides, not TikTok figures.
• A short caption while you test. TikTok says the ad safe zone shrinks with caption length, so test with the caption you will actually use.
• No decoration at the edges that you cannot afford to lose.

The free safe zone checker draws unofficial TikTok margins over your image. Nothing is uploaded.

How do you see what your app does with mixed ratios?

Run a probe post. It answers the question the documentation leaves open, on your phone and your app version.

1. Make three slides: one at 1080 x 1920, one at 1080 x 1350 and one at 1080 x 1080.
2. Give each a thick border and a letter in every corner: A top left, B top right, C bottom left, D bottom right.
3. In the app, tap Add Post (+), then Photo, then Upload, and select the three slides.
4. Set the post to the most restrictive privacy option before you publish. The Creator Academy says the editor lets you change privacy.
5. Open it, swipe through and note which borders and letters you can still see on each slide.
6. Delete the post and write down the phone, the app version and the date.

The slideshow size page has a longer test for a single ratio.

What should you check before you upload?

• Every photo has the same ratio, and you chose it on purpose.
• Wide images are fitted, not filled.
• Must-read text sits inside the strict box from the TikTok safe zone page, and nothing important sits within about 100 px of any edge (our rule of thumb).
• You compared the exported file with the post, not only the screen.
• You tested with your real caption.

Fyslide's image library has a crop tool, so you can crop pictures before they reach a slide, and the app exports PNG or JPG slides at the size of your design. You upload them to TikTok yourself, because posting from the app is Coming soon, included in your lifetime access as an update. The images guide explains the library.
