Use 1080 pixels as your safe starting point for most social posts, then crop for each platform instead of stretching one image everywhere.
TLDR: Most social media images work best when exported at the right pixel size, not just the right visual shape. A square Instagram post should be 1080 x 1080 px, while a Story, Reel, TikTok, or YouTube Short cover should be 1080 x 1920 px. For example, a small bakery posting the same sale graphic to Instagram Stories, Facebook feed, and Pinterest would need three crops: vertical, horizontal, and tall 2:3. Brands that resize properly often see cleaner previews and higher clicks; even a modest 12% lift in tap-throughs can matter during a short campaign.
Social platforms are picky. They compress files, crop edges, and hide text behind buttons. It drives me a little crazy that an image can look perfect in the upload preview, then lose a headline after posting. The fix is simple: design with the correct dimensions, aspect ratio, and safe areas from the start.
Quick Basics: Size, Aspect Ratio, and Resolution
Image size means the width and height in pixels. For example, 1080 x 1350 px.
Aspect ratio is the shape. A 1:1 image is square. A 9:16 image is vertical, like a phone screen. A 16:9 image is wide, like a YouTube thumbnail.
Resolution is often misunderstood. For social media, pixels matter more than print DPI. A 1080 x 1080 px image at 72 DPI and the same image at 300 DPI will usually display the same online. Focus on pixel dimensions, sharp text, and clean compression.
Recommended Social Media Image Sizes
Use these dimensions as a practical guide. Platforms change small details often, but these sizes are reliable for crisp display and clean cropping.
Instagram Image Sizes
- Profile photo: 320 x 320 px, displays as a circle
- Square post: 1080 x 1080 px, 1:1 ratio
- Portrait post: 1080 x 1350 px, 4:5 ratio
- Wide post: 1080 x 566 px, about 1.91:1 ratio
- Stories and Reels: 1080 x 1920 px, 9:16 ratio
For Instagram feed posts, portrait 4:5 often gives you the most screen space. Keep key text away from the top and bottom of Stories, since usernames, buttons, captions, and stickers can cover those areas.
Facebook Image Sizes
- Profile photo: 320 x 320 px or larger
- Cover photo: 851 x 315 px minimum, use 1640 x 624 px for sharper results
- Shared link image: 1200 x 630 px, 1.91:1 ratio
- Feed image: 1080 x 1080 px or 1200 x 630 px
- Stories: 1080 x 1920 px
Facebook cover photos are annoying because desktop and mobile crops differ. Keep logos, faces, and calls to action near the center. Expect to waste time on tiny shifts if your text sits close to the edges.
X Image Sizes
- Profile photo: 400 x 400 px
- Header image: 1500 x 500 px, 3:1 ratio
- Single post image: 1600 x 900 px works well
- Square post image: 1080 x 1080 px
X previews can crop depending on the feed and device. If the image contains a chart, quote, or announcement, place the main message in the center third. Thin text can blur after compression, so use bold fonts and high contrast.
LinkedIn Image Sizes
- Personal profile photo: 400 x 400 px
- Personal background image: 1584 x 396 px
- Company logo: 300 x 300 px
- Company cover image: 1128 x 191 px
- Shared image or link preview: 1200 x 627 px
LinkedIn favors clean, readable graphics. Avoid packing a full slide deck into one image. If you need charts, use a carousel document or split the content into several images.
TikTok Image and Video Cover Sizes
- Profile image: 200 x 200 px or larger
- Video frame and cover: 1080 x 1920 px, 9:16 ratio
- Safe central area: keep text away from the right side and lower section
TikTok is built for vertical content. The right-side icons and bottom caption area can cover important details. Put faces, product names, and hooks in the upper-middle area.
YouTube Image Sizes
- Profile photo: 800 x 800 px
- Thumbnail: 1280 x 720 px, 16:9 ratio
- Channel banner: 2560 x 1440 px
- Banner safe area: 1546 x 423 px centered
- Shorts cover: 1080 x 1920 px
YouTube thumbnails need to be readable at tiny sizes. Use fewer than six words where possible. Faces, strong colors, and one clear subject usually beat cluttered designs.
Pinterest Image Sizes
- Standard Pin: 1000 x 1500 px, 2:3 ratio
- Square Pin: 1000 x 1000 px
- Long Pin: 1000 x 2100 px, use carefully
- Profile photo: 400 x 400 px
Pinterest rewards vertical images because they take up more space in the feed. A 2:3 ratio is the safest choice. Very tall graphics may get cut off, which ruins recipes, infographics, and product guides.
Best File Types and Quality Settings
JPG is best for photos, lifestyle shots, and complex images. PNG is better for logos, icons, and graphics with sharp edges. WebP is efficient, but not every workflow or platform handles it gracefully, so JPG and PNG remain safer defaults.
Keep file sizes reasonable. A huge 12 MB image may upload slowly and still get compressed. For most social posts, aim for under 2 MB when possible, while keeping text crisp. Export at high quality, around 80% to 90% for JPG, then review the final file before posting.
Safe Area Rules That Save Your Design
Correct size does not guarantee a perfect post. Buttons, captions, profile names, and preview crops all get in the way. Use these simple rules:
- Keep text centered: leave padding on every side.
- Avoid tiny type: mobile users should read it in one glance.
- Design separate crops: do not force one image into every format.
- Test on your phone: desktop previews miss mobile problems.
- Use consistent branding: colors and logos should stay recognizable.
Simple Workflow for Resizing Social Images
- Start with the main format. If the campaign is video-first, begin at 1080 x 1920 px.
- Duplicate the design. Create square, portrait, and wide versions.
- Reposition manually. Do not rely only on auto-crop.
- Check text and faces. Make sure nothing critical sits near an edge.
- Export platform-ready files. Name them clearly, such as summer sale instagram story.
A smart set for many campaigns includes 1080 x 1080, 1080 x 1350, 1080 x 1920, 1200 x 630, and 1000 x 1500. That covers the most common feed, story, link, and Pin needs.
Final Checklist Before You Post
- Is the image the correct pixel size?
- Does the aspect ratio match the platform?
- Is the text readable on a small phone screen?
- Are logos and faces inside the safe area?
- Is the file size small enough to upload quickly?
- Have you checked the preview after upload?
Social media image sizing is not glamorous, but it protects your work. A sharp, properly cropped post looks more trustworthy, earns cleaner previews, and wastes less time during publishing. Build a few reusable templates, keep the key dimensions handy, and your content will look intentional on every major platform.
