Frequently Asked Questions
What size should Instagram posts be?
Instagram supports multiple sizes: Square posts at 1080×1080px (1:1), Portrait at 1080×1350px (4:5) which takes more feed space, and Landscape at 1080×566px (1.91:1). Stories and Reels should be 1080×1920px (9:16). Portrait format typically gets higher engagement.
What is the best Facebook cover photo size?
Facebook cover photos display at 820×312px on desktop and 640×360px on mobile. Upload at 820×462px to ensure it looks good on both devices. Keep important content in the center as edges may be cropped differently on mobile views.
What size are YouTube thumbnails?
YouTube thumbnails should be 1280×720px with a 16:9 aspect ratio. The minimum width is 640px. Use JPG, GIF, or PNG under 2MB. Thumbnails significantly impact click-through rates, so use high contrast, readable text, and expressive faces.
What dimensions should TikTok videos be?
TikTok videos should be 1080×1920px with a 9:16 vertical aspect ratio. This is the same as Instagram Stories and Reels. Videos can be up to 10 minutes long. Keep important content away from edges where UI elements appear.
Why do image sizes matter for social media?
Correct sizes ensure your content displays without cropping or quality loss. Properly sized images look professional, load faster, and get better engagement. Each platform optimizes for specific dimensions, so using the right size maximizes visibility and impact.
What image format should I use?
JPG works best for photos with many colors. PNG is better for graphics with text, logos, or transparency. Most platforms accept both. Keep file sizes reasonable for faster loading. For videos, MP4 with H.264 encoding is universally supported.
How often do social media sizes change?
Platforms occasionally update their dimensions, usually when introducing new features or redesigns. Major changes are announced, but minor adjustments happen regularly. This guide is updated for 2025, but always verify critical dimensions on official platform documentation.
Can I use the same image across all platforms?
While you can repurpose content, each platform has different optimal sizes. A 1:1 square works on Instagram but wastes space on YouTube. For best results, create platform-specific versions or design with safe zones that work when cropped to different ratios.
