Threads Post, Image & Video Sizes: Complete Guide

Threads keeps image sizes relatively simple. Unlike platforms with dozens of placement types, Threads supports feed images, carousels, video, and profile photos — and it follows familiar Meta dimensions that you probably already use for Instagram.

That said, getting your dimensions right still matters. Upload the wrong size and your images get compressed or displayed with unnecessary white space. This guide covers every Threads image and video dimension for 2026, plus tips for creating content that looks sharp in the feed.

Quick Reference Table

Key takeaway: Portrait (4:5) at 1080×1350 gives you the most visual impact in the Threads feed. It takes up more screen space than square or landscape and works well for carousels too.

Image Post Dimensions

Threads is flexible with image sizes. The platform does not strictly enforce a single aspect ratio — it displays images without cropping, preserving the original dimensions. However, some sizes perform better than others because of how much screen real estate they command.

Threads accepts images up to 1440px wide, but 1080px is the standard you should target. Portrait (4:5) at 1080×1350 fills the most vertical space in the mobile feed, which means users spend more time looking at your content before scrolling past.

According to Buffer's social media image guide, Threads follows the same general sizing rules as Instagram since both platforms are built on the same Meta infrastructure. If you are already creating content for Instagram at 1080×1350, those images work perfectly on Threads too.

Video Post Specifications

Threads supports video posts up to 5 minutes long. Vertical video (9:16) is the recommended format since Threads is a mobile-first platform.

Upload at 1080×1920 for the best full-screen experience. Threads also accepts square (1:1) and landscape (16:9) video, but vertical fills the entire mobile viewport and tends to get more engagement.

If you create vertical video for Instagram Reels, TikTok, or YouTube Shorts, the same 1080×1920 files work on Threads without any changes. Use a cross-posting tool to distribute your video content across all platforms simultaneously.

Carousel / Multi-Image Posts

Threads allows you to attach multiple images to a single post, creating a swipeable carousel experience.

Threads supports up to 20 images per carousel post. You can mix image sizes within a single carousel — Threads displays each image at its original aspect ratio without forcing a uniform crop.

However, for the most polished look, use the same aspect ratio across all images in a carousel. Portrait (4:5) at 1080×1350 is the best choice for most carousel content because it takes up the most screen space while still being easy to swipe through.

Carousels are ideal for step-by-step tutorials, product showcases, quote collections, and educational content. According to Hootsuite's social media guide, multi-image posts tend to generate higher engagement than single-image posts because they encourage users to interact (swipe) with your content.

Use PostEverywhere's social media calendar to plan your carousel content alongside your regular posts. For more on carousel strategies, check out our guide on how to schedule Threads.

Profile Photo

Your Threads profile photo is synced from your Instagram account. Changing it on one platform updates it on the other. Upload at 320×320 minimum — larger is better for high-density displays.

The profile photo displays as a circle, so keep your logo or face centred. It appears next to every post and comment you make, so it should be instantly recognisable at small sizes. If you manage multiple accounts, a multi-account management tool helps maintain consistent branding across profiles.

Character and Content Limits

While this guide focuses on image and video dimensions, it is worth knowing the text limits for Threads posts since they affect how your visual content is framed.

When you share a link on Threads, the platform generates a preview card with an image pulled from the URL's og:image meta tag. Make sure your website's open graph images are at least 1200×600px for the best link previews.

Tips for Threads Image Optimisation

1. Default to Portrait (4:5) for Feed Posts

Portrait at 1080×1350 takes up the most screen space in the Threads feed. It works well for single images and carousels alike. Since most Threads users browse on mobile, maximising vertical space means more attention on your content.

2. Repurpose Instagram Content Directly

Threads and Instagram share the same Meta infrastructure. Images optimised for Instagram at 1080×1350 (feed) or 1080×1920 (Stories/Reels) work perfectly on Threads without any resizing. If you are already creating content for Instagram, you can post it to Threads immediately.

3. Use Consistent Aspect Ratios in Carousels

While Threads allows mixed aspect ratios in a single carousel, using the same ratio across all images creates a cleaner, more professional swipe experience. Pick 4:5 or 1:1 and stick with it for the entire set.

4. Optimise Link Preview Images

If you share links on Threads, the preview image matters. Set your og:image to at least 1200×600px and make it visually compelling — it is the first thing users see alongside your link. Use our free UTM link builder to track link clicks.

5. Automate Your Multi-Platform Publishing

If you post to Threads, Instagram, Facebook, X, and other platforms, resizing and formatting manually for each one wastes hours every week. PostEverywhere's image resizer and social media scheduler handle the formatting automatically. Learn more about scheduling Threads posts.
