Posting a great photo to social media only to have it look blurry, cropped awkwardly, or compressed into a pixelated mess is frustrating. Each platform has its own preferred image dimensions, aspect ratios, and file size limits. Understanding these specifications helps you present your work at its best, regardless of where you share it.
This guide covers the recommended photo sizes for every major social media platform. We will also cover exporting from editing software for web use, why sRGB matters, and how to balance image quality with file size. Pair this with your Photography Workflow to make social media sharing a seamless part of your process.
A note on these specifications: platforms update their requirements periodically. The sizes listed here reflect current best practices and are designed to give you the best quality. When in doubt, larger is better. Platforms compress and resize your images during upload, and starting with a higher-quality file gives the compression algorithm more to work with.
Feed Posts
Instagram supports three aspect ratios for feed posts: square (1:1), portrait (4:5), and landscape (1.91:1). The portrait 4:5 ratio is ideal for photographers because it takes up the most screen space in the feed, giving your image maximum visual impact.
| Format | Aspect Ratio | Recommended Size | Notes |
|---|---|---|---|
| Square | 1:1 | 1080 x 1080 px | Classic Instagram format |
| Portrait | 4:5 | 1080 x 1350 px | Takes up most screen space in feed |
| Landscape | 1.91:1 | 1080 x 566 px | Least screen space; avoid if possible |
Always upload at 1080 pixels wide at minimum. Instagram will downscale anything larger, but uploading smaller images results in upscaling and visible quality loss.
Stories and Reels
Stories and Reels use a 9:16 vertical format at 1080 x 1920 pixels. This fills the entire phone screen. For photos shared as stories, use this full-screen format. Keep important content away from the very top and bottom edges, as the interface elements can overlap those areas.
Carousel Posts
Carousel posts support up to 10 images. All images in a carousel must share the same aspect ratio. The 4:5 portrait format is recommended for maximum impact. Mix of images and videos is allowed.
| Placement | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Feed Photo | 1200 x 630 px | 1.91:1 | Appears well in the feed |
| Shared Link Image | 1200 x 628 px | 1.91:1 | Preview image for links |
| Cover Photo | 820 x 312 px (desktop) | ~2.63:1 | Crops differently on mobile |
| Profile Photo | 180 x 180 px | 1:1 | Displayed as a circle |
| Event Cover | 1200 x 628 px | 1.91:1 | Standard event header image |
Facebook compresses images aggressively. To minimize quality loss, upload at the recommended resolution, use sRGB color space, and keep file size under 15 MB. Some photographers find that uploading PNG files (for images with text or graphics) results in less compression than JPEG.
Pinterest is a vertical platform. Tall images perform significantly better than wide ones because they take up more space in the Pinterest feed.
| Pin Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Standard Pin | 1000 x 1500 px | 2:3 | Ideal ratio for most pins |
| Long Pin | 1000 x 2100 px | 1:2.1 | More visible but may get truncated |
| Square Pin | 1000 x 1000 px | 1:1 | Acceptable but less screen space |
The 2:3 ratio at 1000 x 1500 pixels is the sweet spot for Pinterest. Images taller than 2:3 may be cut off in the feed. Pinterest recommends a minimum width of 600 pixels, but 1000 pixels produces noticeably sharper results.
TikTok
TikTok is primarily a video platform, but photo carousels and photo posts are increasingly common. Use the 9:16 vertical format at 1080 x 1920 pixels. This is the same as Instagram Stories and Reels.
For photo slideshows or carousel posts, keep text and important elements within the center safe zone, avoiding the top 150 pixels (username and description overlay) and bottom 280 pixels (interaction buttons and description).
YouTube Thumbnails
While YouTube is a video platform, thumbnails are critical for attracting viewers. The recommended thumbnail size is 1280 x 720 pixels with a 16:9 aspect ratio and a minimum width of 640 pixels.
Effective thumbnails are high-contrast images that read clearly even at small sizes. File size should be under 2 MB. Use JPEG or PNG format.
Twitter / X
| Image Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| In-feed Image | 1600 x 900 px | 16:9 | Maximum impact in the feed |
| Two Images | 700 x 800 px each | 7:8 | Side by side in the feed |
| Header/Banner | 1500 x 500 px | 3:1 | Profile header image |
| Profile Photo | 400 x 400 px | 1:1 | Displayed as a circle |
Twitter/X compresses images significantly. Upload at the recommended sizes to start with the best quality. For photos with fine detail, some photographers find that PNG produces better results than JPEG on this platform.
| Placement | Recommended Size | Aspect Ratio |
|---|---|---|
| Feed Image | 1200 x 627 px | 1.91:1 |
| Profile Photo | 400 x 400 px | 1:1 |
| Cover Photo | 1584 x 396 px | 4:1 |
| Article Cover | 1200 x 644 px | ~1.86:1 |
Resolution vs. File Size: Finding the Balance
Resolution (pixel dimensions) and file size (kilobytes or megabytes) are related but different. A high-resolution image has more pixels. A large file size means more data is stored per pixel (less compression). Both affect quality, but they work differently.
For social media, you want enough resolution to fill the display (meeting the recommended pixel dimensions) and enough file size to preserve detail without excessive upload times. A 1080 x 1350 pixel JPEG at quality 85 is typically between 300 KB and 1 MB, which uploads quickly while maintaining good quality.
Over-compressing your images before upload is a mistake. The platform will compress them again during upload. If you pre-compress aggressively, the double compression degrades quality noticeably. Upload at quality 85-95 and let the platform handle the final compression.
Exporting from Editing Software
When exporting from Lightroom For Beginners or Photoshop For Photographers, use these settings for social media output.
- File Format: JPEG for photos. PNG for images with text overlays or graphics.
- Color Space: sRGB. This is critical. Wider color spaces like AdobeRGB or ProPhoto RGB look washed out on screens that do not support them, which includes most phones and browsers.
- Quality: 85-95%. Below 80, compression artifacts become visible. Above 95, file size increases with minimal quality gain.
- Resize: Set the longest dimension to match the platform’s recommendation. Let the software calculate the other dimension based on your aspect ratio.
- Sharpen for screen: Apply a small amount of output sharpening optimized for screen viewing. In Lightroom, choose “Sharpen For: Screen” in the export dialog.
- Metadata: Include copyright information. Strip camera settings and GPS data for privacy.
Why sRGB Matters for Social Media
Every image has an associated color space that defines the range of colors it can represent. sRGB is the standard color space for web and social media. If you export in AdobeRGB or ProPhoto RGB without converting to sRGB, your images may look desaturated or have unexpected color shifts on most displays. See Color Management Photography for a deeper explanation of color spaces.
In Lightroom, set the export color space to sRGB. In Photoshop, use Edit > Convert to Profile and choose sRGB before saving. In Darktable, set the output color profile to sRGB in the export module.
Compression Tips for Maximum Quality
- Export at the right size. Do not upload a 6000px-wide image and let the platform resize it. Export at the recommended dimensions for the platform.
- Avoid re-editing and re-saving JPEGs. Each time you save a JPEG, it compresses again, losing quality. Edit from your original (RAW or TIFF) and export fresh JPEGs each time.
- Use quality 85-90 for most platforms. This gives excellent quality with reasonable file sizes.
- Test your export settings. Upload a test image and view it on different devices. Zoom in to check for compression artifacts, especially in gradients and skies.
- Consider the platform’s compression. Instagram and Facebook compress heavily. Starting with a slightly sharper, slightly more saturated image can compensate for the quality loss during platform compression.
Common Mistakes
- Using the wrong color space. Exporting in AdobeRGB for web use is the most common color management mistake photographers make. Always convert to sRGB for social media. See Color Management Photography.
- Uploading full-resolution files. A 50-megapixel file is massive overkill for social media. The platform will resize it anyway, and the large upload takes longer with no quality benefit.
- Ignoring aspect ratio. Posting landscape images on a vertical platform (like Pinterest) wastes screen space. Crop your images to match the platform’s preferred ratio.
- Not accounting for mobile viewing. Most social media is viewed on phones. What looks great on a desktop monitor may have too-small details on a phone screen.
- Over-sharpening. Sharpening that looks perfect on your editing monitor may look harsh on a phone screen after platform compression.
Try This: Create a Multi-Platform Export
- Choose one of your best photos and open it in your editing software.
- Create three export versions: (a) Instagram portrait at 1080 x 1350, (b) Facebook feed at 1200 x 630, and (c) Pinterest pin at 1000 x 1500.
- For each version, use sRGB color space, JPEG quality 90, and apply screen sharpening.
- Upload each version to its respective platform and view the result on your phone. Note any quality differences.
- Compare how the same photo looks across platforms. Notice how each platform’s compression and display affects the image.
Frequently Asked Questions
Do these sizes change frequently?
Major changes are infrequent, but platforms do update their specifications periodically. The sizes in this guide are current and designed to give you the best results. When platforms increase their supported sizes, uploading at these dimensions will still work well.
Should I create different crops for each platform?
Ideally, yes. A landscape photo that works on Facebook may need to be cropped to portrait for Instagram. Plan for this when you compose and when you edit. Leave some space around your subject to allow for different crops. Strong Photography Composition helps images work across multiple aspect ratios.
Why do my photos look different on different devices?
Screen brightness, color accuracy, and display technology vary across devices. sRGB is the safest color space because it matches most consumer screens. Beyond that, some variation between devices is unavoidable.
Does uploading larger images improve quality?
Not beyond the platform’s display size. Uploading a 4000px image when the platform displays at 1080px does not improve quality. The platform downscales it, and you lose control over how the downscaling is done. Export at the recommended size for the best result.
How do I maintain a consistent look across platforms?
Edit your photo to your satisfaction in your editing software. Then create platform-specific exports with appropriate crops and sizes, but do not change the overall editing. Consistency comes from the editing, not the export settings.
