Why does Twitter crop my vertical photos?

Twitter automatically crops images to a 16:9 aspect ratio in the timeline feed. This means vertical (portrait) photos get cut off at the top and bottom. The crop is applied by Twitter's algorithm which tries to find the 'most interesting' part of the image.

What is the zero-width space trick for Twitter?

Adding a zero-width space character (U+200B) to your tweet text tricks Twitter into not applying the auto-crop, allowing your vertical photo to display at full height. Just copy the invisible character and paste it into your tweet.

Can you post full vertical photos on Twitter in 2026?

Yes. In 2026 you can post vertical photos on Twitter/X by using the zero-width space trick, splitting images into a 2x2 grid, or adding padding around your image. Each method has different trade-offs.

The Story of the Vertical Photo

For years, photographers and artists have struggled with Twitter's auto-cropping. Here's how to beat the machine.

Choose your photo

Find a wide photo or artwork. If it's not wide, crop it to 2:1 first.

Drop it in SplitX

Upload to our homepage. Secure and private.

Pick 2x2 Grid

Select the 2x2 option. Preview the cuts to ensure faces aren't split awkwardly.

Copy Magic Character

Click to copy, then paste into your tweet body or alt text.

Why use the Magic Character?

Using an invisible character in your tweet prevents accidental stacking and keeps your grid perfectly aligned.
