Instagram Image Size Guide

Instagram rewards images that feel native to the feed surface. The right export size depends on whether you are making a square post, a taller feed post, or a full-screen cover.

Review and test note

This guide uses the current 1080 px presets in the tool and distinguishes feed, full-screen, and preview behavior. The numerical example below was checked against the current Crop, Fit, and Blur calculations. Meta-owned documentation is linked for placement references, but organic previews should still be checked in the Instagram app.

Tested example: a 4:3 photo in a 4:5 portrait post

Start with a 2400 x 1800 landscape photo and choose Instagram Portrait Post at 1080 x 1350. Crop to Fill scales the source by height and keeps the central equivalent of 1440 source-width pixels, removing 960 px in total from the left and right. Fit keeps the complete photo at 1080 x 810 and adds 540 px of total background above and below. Blur keeps that same complete 1080 x 810 foreground while filling the portrait canvas behind it. Use Crop for a centered person or product with generous side space; use Fit or Blur when the side context matters.

Instagram uses different visual surfaces for feed posts, Stories, Reels, profile previews, and shared vertical content. The safest practical exports for most creators are 1080 x 1080 for square posts, 1080 x 1350 for portrait feed posts, and 1080 x 1920 for Stories, Reel covers, and full-screen vertical artwork. These sizes are large enough to look sharp on modern phones while staying easy to edit, preview, and repurpose.

When to use square, portrait, and vertical

Use square when you want a stable format that is easy to reuse across carousels, product grids, and cross-platform posts. It is a conservative choice and usually works well when the subject is centered. Use portrait when the post needs more space in the mobile feed. A 4:5 image lets you show a person, product, headline, or lifestyle scene without feeling as cramped as a square crop. Use 9:16 when the asset is meant to behave like a phone-screen design, not a feed card.

The mistake many creators make is designing one image and assuming it will work everywhere. A square product graphic may become too small as a Story. A vertical Story may lose important top or bottom details when reused as a cover. A portrait feed post may look excellent in the feed but still need a cleaner centered subject for profile previews. Before publishing, check the same source image in more than one ratio.

Safe areas and readable text

Instagram images are judged on phones first. Text that looks balanced on a laptop can become weak once it appears in a fast-scrolling feed. Keep text large, short, and high-contrast. Avoid placing the title, logo, product edge, face, or callout label against the outer border. For Stories and Reels, the top and bottom of the screen may compete with app interface elements, captions, stickers, or preview crops. Treat the center of the canvas as the safest area and let the outer edge act as visual breathing room.

Crop, fit, or blur background

Use Crop to Fill when the image is a cover and losing some edge detail is acceptable. This gives the strongest full-bleed look. Use Fit with Background when the image contains a product, full-body photo, screenshot, artwork border, or important detail that cannot be cut off. Use Blur Background when the original image is a different ratio but you still want the final export to feel complete. Blur background is especially useful when turning landscape photos into vertical Stories without plain empty bars.

Common Instagram export mistakes

What to do when the crop looks wrong

If the top of a face, product label, or headline is cut off, switch from Crop to Fill to Fit with Background and compare whether the extra background is less damaging than the crop. If a vertical Story design feels too empty after fitting, use Blur Background and keep the original image centered. If the image is a carousel slide, export one test slide first, check it on a phone, then apply the same crop distance to the remaining slides so the set feels consistent.

Source note: Meta publishes Instagram creative placement specifications through its ads guide. This guide uses those official ratio references as a check, but focuses on organic creator exports and browser preview decisions.

How to resize an Instagram image with Social Image Resizer

  1. Open the free image resizer and upload the original JPG, PNG, or WEBP file.
  2. Choose Instagram Square Post, Instagram Portrait Post, or Instagram Story / Reel Cover from the preset list.
  3. Use Crop to Fill for a full-bleed cover, Fit with Background to preserve the entire image, or Blur Background for a vertical format that still feels native.
  4. Turn on the safe area overlay when the image includes a headline, face, logo, product, or callout label.
  5. Adjust zoom and position until the subject is balanced, then download the current PNG size.

Tips for sharper Instagram exports

Use the largest clean source image you have, especially when the final export will be vertical. Avoid resizing a small screenshot many times in different tools, because each extra editing pass can make type and edges softer. If the image includes text, use a simple font, strong contrast, and enough spacing around the words. For carousel posts, keep the text style and crop distance consistent from slide to slide so the post feels like one designed set instead of separate images stitched together.

When you create a post for more than one platform, export each ratio separately rather than forcing one file everywhere. Instagram, TikTok, Pinterest, and 小红书 may all accept vertical visuals, but the best crop is not always identical. A quick preview in the correct preset is faster than fixing a published image after the title or product edge has been cut off.

FAQ

What is the best Instagram image size?

For most feed posts, 1080 x 1350 is a strong mobile-first choice. For reusable square graphics, use 1080 x 1080. For Stories and vertical covers, use 1080 x 1920.

Should I crop or fit my image?

Crop when the image is meant to fill the frame and edge detail is not important. Fit when you need to preserve the whole product, screenshot, person, or artwork.

Can I use the same image for Instagram and TikTok?

You can reuse the same source image, but check the crop. TikTok covers and Instagram Stories both use vertical artwork, yet their preview surfaces and interface overlays are not identical.
