Threads Sizes & Dimensions Guide (2026): The Complete Reference

Threads has grown beyond being a simple companion app to Instagram. It’s now one of the fastest places to share updates, start conversations, and build a community.

While text remains at the heart of the platform, images and videos often grab attention first. If your media looks blurry, cropped, or awkwardly framed, it’s easy for people to scroll past.

This guide covers the latest Threads image and video sizes for 2026, including the recommended dimensions, aspect ratios, file formats, and size limits. You’ll also learn a few practical tips to help every post look its best and make the most of Threads’ mobile-first feed.

Threads Sizes at a Glance (2026)

Threads keeps things simple compared to most social platforms. At the moment, there are just two primary media formats you need to optimize for: posts and videos.

Both work best in a 1080 × 1920 pixel vertical format, making it easy to create content that looks great across the app.

In the sections below, we will take a deeper dive into each format, along with supported file types, compression tips, and best practices to help your content stand out in the Threads feed. So, keep reading!

Why Threads Image Sizes Matter

Threads may be known for text-based conversations, but visuals still play a big role in capturing attention. Since the app is designed primarily for mobile devices, images and videos that use the recommended vertical format naturally take up more space in the feed, making them harder to miss as people scroll.

Using the correct dimensions also helps preserve image quality and reduces unwanted cropping or compression. Instead of shrinking or trimming your media to fit, Threads can display it more naturally, giving your photos, graphics, and videos a cleaner, more professional appearance.

Threads Post Image Size

The recommended image size for a Threads post is 1080 × 1920 pixels with a 9:16 aspect ratio. This vertical format fills more of the mobile screen, helping your content stand out as people scroll through the feed.

Threads also supports square and landscape images, so you aren’t limited to one format. However, wider images occupy less space in the feed and can be easier to scroll past. If your goal is to maximize visibility and create a more immersive experience, a vertical image is usually the better choice.

When designing your posts, keep your main subject close to the center of the image. This helps prevent important details from being cropped or partially hidden as Threads adapts your content to different screens.

Threads Video Size

Threads videos use the same recommended dimensions as image posts: 1080 × 1920 pixels with a 9:16 aspect ratio. Vertical videos naturally take up more screen space, making them easier to notice and more enjoyable to watch on mobile devices.

Videos can be up to 5 minutes long, giving you plenty of room to share tutorials, product demonstrations, behind-the-scenes clips, or short-form storytelling.

For the best results, export your videos in MP4 format before uploading, as it provides excellent quality while keeping file sizes manageable.

Like images, high-resolution videos tend to hold up better after Threads applies its compression. Starting with a sharp source file helps preserve quality and gives your audience a better viewing experience.

Threads File Formats & Compression

Using the right file format is just as important as choosing the correct dimensions. Threads automatically compresses uploaded images and videos to improve loading speeds, so starting with the right format helps preserve quality after your content has been processed.

JPG and JPEG

JPG and JPEG are the best choices for most photographs. They offer an excellent balance between image quality and file size, making them ideal for everyday posts.

PNG

PNG works best for graphics, illustrations, screenshots, infographics, and images that contain text. It preserves sharp edges better than JPG, making logos and branded graphics appear cleaner after upload.

GIF

Threads also supports GIF files, allowing you to share lightweight looping animations. They’re a good option when you want to add movement without creating a full video.

MP4

MP4 is the recommended format for Threads videos. It provides high-quality playback while keeping file sizes relatively small, making uploads faster and ensuring good compatibility across devices.

MOV

MOV files are also supported and can produce excellent video quality, particularly if you’re exporting directly from video editing software. If file size becomes an issue, converting to MP4 is usually the better option.

How Threads Compresses Media

Like other Meta platforms, Threads re-encodes images and videos after they’re uploaded.

While you can’t disable this compression, you can reduce visible quality loss by uploading media at the recommended 1080 × 1920 pixel resolution, using high-quality source files, and choosing the appropriate format for your content.

Photos generally perform best as JPG files, graphics as PNG, and videos as MP4.

Best Practices for Threads Images and Videos

A few small adjustments can make a noticeable difference in how your content looks on Threads. Following these best practices helps your posts appear sharper, more engaging, and better suited to the platform’s mobile-first experience.

Use Vertical Media Whenever Possible

Threads is built around a mobile feed, so 1080 × 1920 px (9:16) images and videos usually make the strongest impression. They occupy more screen space and naturally draw more attention than wider formats.

Keep Your Subject in the Centre

Although Threads supports multiple aspect ratios, slight cropping can occur in previews. Positioning people, products, logos, or other important elements near the center helps ensure they remain fully visible.

Upload High-Resolution Files

Always start with high-quality images and videos. Better source files hold up much better after Threads applies its compression, resulting in sharper-looking content.

Export Videos as MP4

MP4 provides the best combination of quality, compatibility, and file size. It also helps reduce upload times while maintaining smooth playback across different devices.

Make the First Frame Count

The opening frame of your video is often what people notice first as they scroll. Choose a clear, eye-catching opening scene that encourages viewers to stop and watch.

Preview Before Publishing

Before posting, check how your image or video appears on a mobile device. A quick preview can help you catch alignment, cropping, or quality issues before your audience sees them.

Common Threads Size Mistakes to Avoid

Even great content can lose its impact if it’s uploaded using the wrong dimensions or file settings. Avoid these common mistakes to keep your Threads posts looking professional.

Uploading Low-Resolution Images: Small or heavily compressed images can appear blurry after they’re uploaded. Starting with high-resolution media helps maintain better quality throughout the posting process.

Using Wide Landscape Images: Landscape images are supported, but they appear much smaller in Threads’ vertical feed. Whenever possible, use portrait images to give your content more visual presence.

Posting Videos in the Wrong Format: Using unsupported or less efficient video formats can lead to larger file sizes or slower uploads. MP4 remains the safest choice for most creators.

Placing Important Content Near the Edges: Text, faces, or logos positioned too close to the edges may not display as cleanly in previews. Keeping your main subject closer to the center provides a safer layout.

Uploading Long Videos Without Editing: Although Threads allows videos up to five minutes long, viewers often decide within the first few seconds whether to continue watching. Trim unnecessary sections and get to the point quickly to improve engagement.
