Frequently Asked Questions
What size should Instagram posts be?
Instagram recommends 1080×1080 pixels for square posts, 1080×1350 for portrait (4:5 ratio), and 1080×566 for landscape (1.91:1 ratio). For Instagram Stories and Reels, use 1080×1920 pixels (9:16 ratio). Uploading images at these exact sizes prevents Instagram from compressing them and degrading quality.
What are the correct dimensions for a Facebook cover photo?
Facebook displays cover photos at 820×312 pixels on desktop and 640×360 pixels on mobile. To ensure your cover photo looks good on both, design it at 820×462 pixels and keep important content centered. For Facebook post images, use 1200×630 pixels for the best display in the news feed.
What is the ideal YouTube thumbnail size?
YouTube thumbnails should be 1280×720 pixels with a minimum width of 640 pixels, using a 16:9 aspect ratio. Keep file size under 2MB and use JPG, PNG, or GIF format. Thumbnails at 1280×720 display sharply across all devices — from mobile phones to large desktop monitors — and are used by YouTube when generating video previews.
