Where 1080 × 1350 is asked for
Meta's Ads Guide recommends a 4:5 shape at 1440 × 1800 pixels for image ads in the Instagram feed and lists 4:5 (400 × 500) as the tallest shape it accepts there, with a minimum width of 500 pixels. 1080 × 1350 has exactly that 4:5 shape at three quarters of the recommended width.

A 1080 × 1350 image has 1,458,000 pixels, about 1.5 megapixels. A portrait photo from a phone, 3,024 × 4,032 pixels in 3:4, is a little taller than wide; 4:5 is a little less tall, so Crop to fill trims only the top and bottom.

What happens to common photo sizes
Each row shows what the three shape options make of a typical picture at 1080 × 1350, worked out with the same math the tool uses. Crop to fill, the preset, always gives exactly 1080 × 1350. Trimmed pixels are counted on the original photo, before it is scaled.

Crop to fill always keeps the middle of the picture. To choose which part stays, crop it first in the image cropper and then resize it here.
File size of a 1080 × 1350 image
How large the file gets depends on the picture and the format. For JPEG, Wallace's guide gives a rule of thumb in bits per pixel: 0.25 for moderate to good quality, 0.5 for good to very good, 0.75 for excellent and 1.5 for results usually hard to tell from the original, for color images of moderate detail. Over the 1,458,000 pixels of 1080 × 1350, that comes to about 46 KB, 91 KB, 137 KB and 273 KB, in the same order.
| Bits per pixel | Expected quality | JPEG at 1080 × 1350 |
|---|---|---|
| 0.25 | Moderate to good | 46 KB |
| 0.5 | Good to very good | 91 KB |
| 0.75 | Excellent | 137 KB |
| 1.5 | Usually hard to tell from the original | 273 KB |
These are estimates for JPEG, not a promise: a detailed photo needs more, a flat graphic less, and PNG stores every pixel without loss. The tool's quality slider sets JPG and WebP quality, and the list under the tool shows the real size of every file. If a form sets a limit in KB, resize first and then compress the image to 200 KB or any other size with compress to target size.
How to resize an image to 1080 × 1350
Drop one or more images above. Width 1080 and height 1350 are already filled in, with Crop to fill selected. Every image is resized right away; change the shape option, the format or the quality and they are all redone. Download each image or all of them as a ZIP. The file names end in -1080x1350, so you can tell them apart from the originals.
Need a different size? One size down is 1080 × 1080, one size up 1080 × 1920. Type any width and height into the fields, or use the image resizer with percent and max size modes. To make the file smaller without changing the pixels, use the image compressor.

Frequently asked questions
What happens to a 12-megapixel photo resized to 1080x1350?
A 12-megapixel phone photo of 4,032 × 3,024 pixels is 4:3. With Crop to fill, the preset, it becomes exactly 1080 × 1350, and 806 pixels are trimmed from each side of the original first, 40% of the picture. Fit and pad gives 1080 × 1350 with the whole photo scaled to 1,080 × 810 and bands of 270 pixels above and below. Fit inside keeps the shape and returns 1,080 × 810. All three shrink the photo, which keeps it sharp.
Why does my landscape photo lose so much at 1080 × 1350?
Because a landscape photo is wider than tall, and 4:5 is taller than wide. Crop to fill keeps the full height and trims the sides: a 3,000 × 2,000 camera photo keeps 1,600 of its 3,000 pixels in width, and a 4,032 × 3,024 phone photo keeps about 2,419 of 4,032. To keep everything, choose Fit and pad.
Is 1080 × 1350 the same shape as 1440 × 1800?
Yes. Both are 4:5: 1080 ÷ 1350 and 1440 ÷ 1800 are both 0.8. The larger size has about 1.78 times as many pixels, so resize to 1440 × 1800 when your photo is that large and you want the size Meta's Ads Guide recommends for feed image ads.
What aspect ratio is 1080x1350?
1080 × 1350 has an aspect ratio of 4:5: the width is 0.8 times the height. Any picture of the same shape resizes to it without trimming or bands.
Are my images uploaded to resize them to 1080 × 1350?
No. Your browser opens each image, draws it at the new size and saves it on your own device. Nothing is sent to a server.
