About This Tool

Enter any width and height in pixels to instantly see the aspect ratio, total megapixels, the common resolution name (like 1080p or 4K), and a recommended bitrate range for that resolution — useful when setting up an export or checking a platform's requirements.

How to Use This Tool

Step 1 — Enter your width and height in pixels.

Step 2 — Click Calculate to see all four values at once.

Common Mistakes to Avoid

Assuming all "1080p" videos are 1920x1080. Vertical video for Shorts/Reels is often 1080x1920 — same pixel count, different orientation.

What is considered 4K resolution?

3840x2160 pixels (UHD), sometimes 4096x2160 for true cinema 4K.

Why does the recommended bitrate vary?

Higher resolutions need more bitrate to avoid visible compression artifacts, since there are more pixels of detail to encode per frame.
