Instagram image sizes

Instagram displays images at a width of 1080 px. Only the height changes by format. The 4:5 portrait takes up more room in the feed, but the profile grid crops it to a square.

Placing text so nothing gets cut off

  • Leave a margin of about 54 px around text: the white guide shows it.
  • In portrait, keep the key message inside the central 1080 × 1080 px square (yellow guide), or the profile grid will crop it.
  • For stories, avoid the top and bottom 250 px, where your name and the reply bar appear.
  • A headline of 6 to 10 words in big letters reads better than a paragraph.

Make your post in three steps

Pick one of the nine templates and a palette, fill in the headline, text, badge and handle, then adjust each element with your finger or mouse. Add your photo in a “+” frame or with the Image button. Download as a JPG (light, ideal for phones) or a PNG. Your design is saved on your device.

Frequently asked questions

What size is an Instagram post?
1080 × 1080 pixels for a square, or 1080 × 1350 pixels for a 4:5 portrait. Portrait takes up more room in the feed.
What size is an Instagram story?
1080 × 1920 pixels, a 9:16 ratio. Keep about 250 pixels clear at the top and bottom for the interface.
Why is my portrait post cropped on my profile?
The profile grid shows square thumbnails. Keep key text inside the central 1080 × 1080 pixel square, the yellow guide in the preview.
Should I use JPG or PNG for Instagram?
JPG is lighter and fine for photos. PNG keeps letters and flat colors sharper. Instagram recompresses both.
Can I use my favorite font?
The editor offers eleven web-safe fonts that exist on every device. Fonts installed only on your computer would not appear in the final file.
