Instagram Image Sizes for News Posts (2026): The Complete Guide

If you run a news or meme page on Instagram, the single fastest way to lose reach is to post a graphic at the wrong size. Instagram crops it, your headline gets clipped, and the post looks amateur in a feed full of polished competitors. This guide covers the exact sizes that work for news graphics in 2026 — and which one to default to.

The short answer: use 1080×1350

For news posts, 1080×1350 pixels (4:5 portrait) is the size to beat. It takes up the most vertical space allowed in the feed, which means your headline is physically larger on a phone screen than the same post at 1080×1080. More screen space is more stopping power, and stopping power is the whole game for news content.

Square (1080×1080) still works and is safe, but you're voluntarily giving up about 25% of the screen height. Unless you have a specific reason to go square, portrait is the better default.

Quick-reference table

Format	Pixels	Aspect ratio	Use it for
Feed portrait	1080×1350	4:5	Default for news graphics
Feed square	1080×1080	1:1	Carousels, grid consistency
Stories / Reels	1080×1920	9:16	Breaking news, reshares
Profile grid thumb	1080×1080 center	1:1 crop	How the feed crops your portrait post

Safe zones matter more than the canvas

Instagram shows your post at full 4:5 in the feed, but the profile grid crops it to a center square. If your headline runs to the very top or bottom of a 1080×1350 canvas, it'll be cut off when someone browses your profile.

Keep anything critical — the headline, your logo, the source credit — inside the center 1080×1080 region. Treat the top and bottom ~135px strips as bleed: good for background imagery, risky for text.

File format and quality

• Format: JPG for photographic backgrounds, PNG only if you need crisp flat color or transparency.
• Color: sRGB. Instagram assumes it, and anything else shifts on upload.
• Compression: export at high quality. Instagram re-compresses on its end, so starting from a soft file means the final post looks muddy. Start clean.
• Resolution: 1080px on the short edge is the sweet spot. Going larger (e.g. 2160px) doesn't help — Instagram downscales to 1080 anyway.

The text problem nobody warns you about

The hardest part of a news graphic isn't the size — it's keeping the headline legible. A great background with an unreadable headline is a dead post.

This is also where a lot of AI image tools fall down: when text is drawn into a generated image, it garbles, misspells, and warps. For a news page, that's fatal — credibility is the product. The fix is to render the headline as real text on top of the image, never as part of the generated pixels. That's exactly how BlurbStack builds posts: the AI generates the background, but the headline and caption are laid out by a deterministic template engine, so they're always sharp and spelled correctly. (More on that in how to make Instagram news graphics.)

So what should you default to?

Portrait, 1080×1350, headline and logo inside the center square, exported as a high-quality sRGB JPG. That covers ~90% of news posts. Reach for square when you're building a carousel, and 9:16 when you're pushing something to Stories.

If you're producing these at volume across multiple brands, doing it by hand in a design tool gets slow fast — that's the problem BlurbStack was built for: paste a link, get a correctly-sized, on-brand post in seconds.
