Compose a portrait post on a 4:5 canvas
A 1080×1350 image gives a portrait composition more vertical space than a square. This preset is a practical 4:5 working canvas for an Instagram post, not a promise about every display surface. Fit is selected initially so a landscape original is not cropped without your choice.
Get a better result
Choose Fill when your subject can tolerate cropping, then move the focus to protect faces and lettering. Leave space around important elements because the destination may show another preview crop. A story or reel cover needs a different tall canvas.
A quick workflow
- Choose an original and review the 1080×1350 dimensions.
- Select Fit or a deliberate Fill crop and inspect the subject’s placement.
- Download and review the image again in the intended Instagram composer.
When this tool helps
Prepare portrait feed artwork or a consistent set of carousel images. Use the story preset for a 9:16 working canvas and the square preset when the design is intended to be 1:1.
