Instagram Portrait Resizer — 1080×1350
Resize images to Instagram portrait post size 1080×1350 (4:5). Maximum feed real estate.
About the Instagram Portrait
This tool outputs the exact Instagram portrait post (4:5) dimensions of 1080×1350 pixels. Cover mode center-crops to fill the frame edge-to-edge; contain mode fits the whole image with padding. Batch up to 10 images — every one comes out at the precise size the platform expects.
How it works
The tool outputs exactly 1080×1350 pixels — Instagram's largest allowed post footprint, which occupies noticeably more screen than a square in the feed. Fit modes reconcile your source shape: cover crops in, contain pads out, stretch distorts (rarely what you want).
How to use it
Add up to 10 images, pick cover or contain fitting, choose a pad color if containing, and process. Review each preview at feed scale in your head — then download the batch.
Supported formats & limitations
Accepts .jpg, .png and .webp up to 30MB each, 10 per run. Square sources crop only their edges at 4:5; wide landscapes lose sides — portrait-oriented sources fit this frame most naturally.
Common use cases
Feed posts that demand attention (4:5 outperforms square for scroll-stopping), lookbook and editorial layouts, and campaign grids mixing squares and portraits where each format needs its own master file.
Frequently asked questions
What size is instagram portrait?
1080×1350 pixels — this tool outputs exactly that size. Cover mode center-crops your image to fill the frame; contain mode keeps the whole image visible and pads the difference.
What is 1080×1350 in cm or inches?
Social platforms define sizes in pixels only, because physical size depends on the screen. For reference: printed at 300 DPI, 1080×1350 px measures about 9.1×11.4 cm (3.60×4.50 in).
Cover or contain?
Cover fills the frame completely (crops edges); contain shows the full image with padded bars. Use cover for photos, contain for logos or graphics you don't want cropped.
Can I resize several instagram portrait images at once?
Yes — drop up to 10 files and every one comes out at exactly 1080×1350 px. Results can be downloaded individually or as a single ZIP.
