Instagram portrait post size: 1080 × 1350

How it works

1. Drop one or more photos. Full-length portraits, product shots and vertical landscapes work best in 4:5.
2. Fill and crop is preselected: a 4:5 frame appears on the photo, as large as it fits. Drag it to choose what stays; everything outside is trimmed.
3. Press Resize for Instagram. Each output is exactly 1080 by 1350 pixels and is named with the size, e.g. photo-1080x1350.jpg.
4. Download and post. Because the ratio already matches, Instagram's crop screen will not ask you to trim anything.

Frequently asked questions

What size is a Instagram portrait post?

The Instagram portrait post size is 1080 × 1350 pixels (4:5), the tallest a photo appears in the feed. 4:5 is the tallest aspect ratio Instagram allows in the feed. At 1080 pixels wide that is 1350 pixels tall, and it occupies about 30% more screen than a square, which is why photographers and shops prefer it. Anything wider than 1080 is downscaled by Instagram anyway.

Which part gets cropped?

You decide. The frame is taller than most photos, so on a landscape photo it covers only a narrow column that you slide left or right, while on a typical 3:4 phone portrait it covers almost everything and only a thin strip at the top or bottom goes. The frame starts centred.

Can I keep the whole photo?

Choose Fit inside: the image is scaled to fit within 1080×1350 without cropping and the remaining space is filled with white (or left transparent for PNG), so the file is still exactly 1080×1350.

Is anything uploaded?

No. Resizing runs in your browser and nothing is sent to Nouplo. The free plan allows 3 files per run, 20 MB per file and 5 runs per day; Pro removes those limits.

JPG or PNG?

JPG for photos, which is what Instagram stores anyway. PNG keeps text sharper for announcement graphics and carousel slides with diagrams.
