Social Media Sizes

Every social media platform has specific image dimension requirements for each content type. Use the wrong size and your image gets cropped, stretched, or pillarboxed in ways you didn't intend. Profile pictures get circular-cropped. If your logo or face isn't centered, the edges will be cut. Cover photos display at different proportions on desktop and mobile. Knowing the correct dimensions before you design or upload saves you from repeated exports and surprise cropping. Use the reference above to find the right dimensions, then click "Resize my image to this size" to resize your image directly. No separate tool, no upload to a server.

How to use

1. Pick your platform. Click the platform tab (Instagram, YouTube, TikTok, Facebook, LinkedIn, Twitter/X, Pinterest, and more) to see all supported image formats for that network.
2. Select your format. Each platform has multiple content types, such as profile picture, cover photo, post image, Story, Reel, video thumbnail, and more. Click the format to see its exact dimensions and a scaled aspect-ratio preview.
3. Note the dimensions. The Width and Height shown in pixels are the exact recommended upload sizes. The animated shape in the preview illustrates the aspect ratio so you can immediately see whether it's square, portrait, or landscape.
4. Resize your image. If you have an image to resize, click "Resize my image to this size" in the format preview. The resizer opens below with that format already pre-selected. Drop your image, choose crop or pad mode, and download.

Tips for best results

• Design at 2× for retina displays. All the dimensions listed are the minimum display sizes. For sharp rendering on retina and high-DPI screens (iPhone, modern Macs, many Android devices), design and export at 2× the dimensions shown, so a 1080×1080 Instagram post should ideally be designed as 2160×2160 and let the platform downscale it.
• Use safe zones for profile pictures. Profile photos are displayed in circles or rounded squares depending on the platform. Any content near the edges of a square profile image may be cropped. Keep the main subject centered and within the central 80% of the frame.
• Cover photo safe zones differ on mobile and desktop. Platform cover photos are cropped differently on mobile and desktop views. Keep important content (text, logos, faces) in the central portion to ensure they're visible in both contexts.
• Compress before uploading. Platforms apply their own compression on top of your upload. If your image is already large, run it through the image compressor first to control the quality yourself and reduce unnecessary re-compression artifacts.

Why use PixMidas

• Reference and resize in one place. Find the correct dimensions and resize your image without switching tools. The resizer opens inline when you click "Resize my image to this size" on any supported format.
• Current dimensions. Platform image specs change when platforms redesign their interfaces or add new content types. This reference reflects current specifications rather than outdated guides.
• 100% private. All image resizing uses the Canvas API on your device. Your image is never uploaded to any server.
• No account needed. Free and instant, no signup required.

Frequently asked questions

What are the correct Instagram image sizes?

Instagram supports three post aspect ratios: square at 1:1 (1080×1080 px), portrait at 4:5 (1080×1350 px, recommended by Meta for maximum reach), and landscape at 1.91:1 (1080×566 px). Instagram Stories and Reels use 9:16 at 1080×1920 px. Profile pictures are displayed at 110×110 px on mobile but should be uploaded at at least 320×320 px. Instagram applies quality reduction on images; upload at higher resolution to ensure the final result looks sharp.

What size should a Facebook cover photo be?

Facebook Page cover photos are 851×315 px. They display slightly differently on desktop (820×312) and mobile (640×360), so keep important content (text, logos) centred and away from the left side, where the profile picture overlaps.

What is the best size for a Twitter/X header image?

Twitter/X profile headers display at 1500×500 px at a 3:1 aspect ratio. The profile picture overlaps the lower-left portion of the header. Keep important content away from the left 20% of the image and the bottom edge to avoid overlap.

What size should a YouTube thumbnail be?

YouTube thumbnails should be 1280×720 px (16:9 aspect ratio) at a maximum file size of 2 MB. The minimum accepted is 640×360 px but 1280×720 provides sharp rendering on all screens. Use the image compressor if your thumbnail exceeds the 2 MB limit.

Do image requirements change frequently?

Profile picture and cover photo dimensions are relatively stable. Ad format specifications and newer content types (Reels, Stories) change more frequently. Always verify the latest specs in the platform's official creator or advertiser documentation when preparing materials for a campaign.

Why does my uploaded image look different than what I designed?

Platforms apply their own compression and cropping after upload. Most compress images, sometimes aggressively, which reduces quality and can shift colors slightly. Uploading at higher resolution gives platforms more to work with before compression. Some platforms also enforce aspect ratios by cropping rather than stretching, so if your image doesn't match the expected ratio, edges may be removed. Always use the exact required aspect ratio and preview before publishing.
