Making X post images that don't get cropped

By PC Wall Art Team

An image in a post on X gets seen in many places: the main timeline on phones and desktop, the expanded view, multi-image grids, embeds on other sites and link previews. Each can show a different part of it. The simplest way to avoid surprises is to pick a shape that crops well and keep anything important away from the edges.

PC Wall Art is not affiliated with X Corp. The advice below comes from how the service displays images today. X changes its layouts from time to time, so treat the exact crops as a guide rather than a rule.

The three shapes that work

16:9 is the safe default. It matches the frame X uses for many previews and embeds, so it's the shape least likely to be cropped anywhere.

4:5 portrait takes more vertical space in the mobile timeline, which is why it's popular for quotes and announcements. In some places, though, it can be shown cropped to a wider frame, so the top and bottom aren't guaranteed to be visible.

1:1 square sits in between. It loses less than a portrait image in a wide crop and still takes more room than 16:9.

Images much taller than 4:5 are the most likely to be cropped hard. Long screenshots and infographics usually get cut, and readers have to tap to see the rest.

Where the crops happen

Single images. On the X apps, a single image within the common range of shapes is usually shown whole. The crop risk comes from other places the post appears: some embeds, previews and older or third-party clients center-crop to a wider frame.

Two images. Two images in one post sit side by side, and each is cropped to a tall tile, close to 7:8. A 16:9 image loses a lot of its width in this layout.

Three and four images. The grid gets tighter. With four images each one becomes a small tile, and the center of each image is all that's guaranteed to show.

In every case the crop is centered. That gives you a simple rule: the middle of the image is the only part you can count on.

Use a safe area

A safe area is the region that survives the tightest crop you expect. For a single image, plan for a centered 16:9 crop:

• On a 1080 × 1350 portrait image, the 16:9 band is the middle 1080 × 608 pixels. Text above or below it may be hidden in some views.
• On a 1200 × 1200 square, the band is the middle 1200 × 675 pixels.
• A 1600 × 900 image is already 16:9, so the whole frame is safe.

Leave a margin of about 5% inside the safe area too. Rounded corners, video-style overlays and the "ALT" badge can sit on the edges.

The X post image maker on this site draws the 16:9 band as a guide on the preview and can keep your text inside it automatically. The guides don't appear in the downloaded file.

Text on images

Text on a post image has to survive three things: the crop, compression and a small screen.

Size. On a phone, a 1600 × 900 image is shown at roughly a quarter of its width. Text that looks fine on your monitor can end up tiny. As a rough check, the main line of text should be at least 5% of the image height. If you can't read it with the preview zoomed out to phone width, it's too small.

Length. One idea per image. Under about 25 words works best. If you need more, put it in the post text, which people can read in full and which search can find.

Contrast. X re-encodes uploaded images to save bandwidth, which softens fine detail. Thin, light text on a busy background suffers most. Use a solid color behind the text, or a darker card, and keep strokes reasonably bold.

Export. Upload the image at the exact size you designed it. If you upload something much larger, X will scale it down and the text gets softer. PNG keeps flat colors and text clean before X's own compression.

The caption still matters

An image post is two things: the picture and the post text. The text is what people read first in many layouts, and it's what screen readers announce. Standard accounts get 280 characters, and X counts them in a specific way:

• Most letters, digits and punctuation count as one.
• Chinese, Japanese and Korean characters count as two.
• Most emoji count as two.
• Any link counts as 23, however long it is.

The counter in the post maker follows those rules so you can write the caption next to the image and copy it when you're done.

Add alt text when you post. X lets you describe each image in up to 1,000 characters. If the image is mostly text, paste that text into the description so people using screen readers get the same message.

A quick checklist

1. Pick 1600 × 900 unless you have a reason for portrait or square.
2. Keep text and faces inside the centered 16:9 band.
3. Make the main text big enough to read at phone width.
4. Put a calm background or a card behind the text.
5. Upload at the size you designed.
6. Write the caption, check the count, and add alt text.
