Understanding Instagram Size 4:5 — What It Means
Instagram size 4:5 refers to a vertical aspect ratio that has become one of the most effective formats for posts on the platform. An aspect ratio measures the relationship between width and height — in the case of 4:5, the width is 4 units and the height is 5 units.
Instagram originally gained popularity with square (1:1) posts, but over the years, vertical formats like 4:5 have dominated because they take up more space in the feed, drawing more user attention.
This format is particularly popular for portrait photography, tall product images, infographics, and content where you want to maximize vertical screen real estate without getting cropped in previews.

Aspect Ratio: 4:5 vs 1:1 vs 16:9
Understanding how 4:5 compares with other common aspect ratios helps you choose the right format for your content.
| Aspect Ratio | Dimensions (Common) | Best Use Cases | Feed Presence |
|---|---|---|---|
| 4:5 | 1080 x 1350 px | Portrait shots, vertical product photos, infographics | High – occupies more vertical space |
| 1:1 | 1080 x 1080 px | General posts, minimalistic layout, symmetrical images | Medium – balanced but less scroll coverage |
| 16:9 | 1080 x 608 px | Wide landscapes, cinematic views, videos | Low – less vertical space in feed |
With the 4:5 format, your image is taller than it is wide, which makes it stand out visually compared to a square or wide image.

Recommended Pixel Dimensions for 4:5
For optimal quality on Instagram, the recommended pixel size for a 4:5 image is:
Width: 1080 pixels
Height: 1350 pixelsWhy 1080 pixels? That’s Instagram’s standard image width for posts. Height adjusts according to aspect ratio. If your image is taller than 1350 pixels, Instagram will crop it automatically to fit the 4:5 maximum height.

How 4:5 Format Affects Feed Appearance and Engagement
One of the main reasons 4:5 has become important on Instagram is feed visibility. Taller images:
- Occupy more vertical space on the user’s scrolling screen.
- Can slow down the scroll, increasing the likelihood of engagement.
- Make detailed visuals easier to showcase.
Instagram posts in 4:5 can lead to higher interaction rates simply because they command more attention — especially when combined with compelling captions and strategically placed subject matter.

Best Practices for Designing Vertical Images in 4:5 Ratio
When creating vertical posts in the Instagram size 4:5, follow these tips:
- Centralize Key Elements
- Keep the focus subject in the center area so cropping doesn’t affect it.
- Leave Safe Margins
- Avoid placing important text or objects too close to edges — captions and UI icons can overlap.
- Use High-Resolution Graphics
- Instagram compresses images; high resolution helps preserve clarity.
- Balance Composition
- Apply photography rules like the rule of thirds to keep the subject engaging.
- Think Mobile-First
- Remember, most Instagram users browse on mobile — ensure text is readable on small screens.

Tools and Apps to Crop or Resize Images to 4:5 Easily
Getting your visuals into the right aspect ratio is crucial. You can use:
- Adobe Photoshop / Lightroom — Full control over crop and export settings.
- Canva — Pre-made Instagram 4:5 templates for quick design.
- VSCO / Snapseed — Mobile-friendly cropping with aspect ratio presets.
- Figma — Ideal for graphic-heavy posts and infographics.
- Instagram’s Built-in Crop Tool — Useful when uploading directly from your camera roll.
These tools let you lock the aspect ratio to 4:5, ensuring the final export meets Instagram’s height restriction.

Maintaining Quality When Resizing or Compressing
Instagram applies its own compression to images. To keep images sharp in the 4:5 format:
- Start with high-resolution source images (at least 300 DPI).
- Use lossless formats like PNG for graphics with text, and high-quality JPEG for photos.
- Avoid repeated resizing — each change can introduce artifacts.
- Pre-sharpen images very slightly before uploading.
Also, keep your color profiles in sRGB mode to match Instagram’s display environment.

Examples in the 4:5 Format
Here are some common use cases for the Instagram size 4:5 ratio:
- Portrait Photography — Professional portraits use vertical space to highlight the subject.
- Infographics — Tall infographics show more data without splitting into multiple images.
- Product Photography — Long items (like dresses, posters, and bottles) benefit from vertical framing.
- Event Posters — A taller format helps fit event details clearly while being visually striking.

Mistakes to Avoid in 4:5 Instagram Posts
While 4:5 is optimal, there are pitfalls:
- Cut-off Text — Placing text too close to the top/bottom risks cropping in feed previews.
- Stretched Images — Incorrect resizing that changes proportions can distort elements.
- Poor Resolution — Using low-quality images becomes more obvious at larger display sizes.
- Ignoring Composition — Tall images require thoughtful layout to avoid dead space.

How to Preview 4:5 Posts Before Publishing
Testing your content before going live is a great way to avoid mistakes. Here’s how:
- Use Instagram Drafts — Upload and save as draft to view how it appears in feed.
- Third-Party Preview Apps — Apps like UNUM or Planoly allow simulated feed previews.
- Story Test — Share a temporary story with the 4:5 asset to gauge real device appearance.
- Figma/Canva Mockups — Insert your design into a phone mockup to replicate feed view.
By previewing, you ensure text readability, image proportion, and aesthetic alignment within your account’s style.
