Best YouTube Thumbnail Size - Complete Guide
Do you want to know the perfect size for YouTube thumbnails? This guide will tell you everything about thumbnail sizes in simple words that anyone can understand.
Quick Answer
The best YouTube thumbnail size is 1280 pixels wide and 720 pixels tall.
This is written as 1280 x 720 pixels.
What Does This Mean?
Pixels are tiny dots that make up a picture on your screen. More pixels mean a clearer, sharper picture. The size 1280 x 720 means:
- 1280 dots going left to right (width)
- 720 dots going up and down (height)
Why This Size?
YouTube likes this size because:
- It looks clear and sharp
- It fits perfectly on all screens
- It works on computers, phones, and TVs
- It is HD quality (High Definition)
Other Sizes That Work
YouTube also accepts other sizes, but they should follow this rule:
- Width must be at least 640 pixels
- The shape should be a rectangle (16:9 ratio)
Here are some other good sizes:
- 1920 x 1080 (Full HD - very high quality)
- 1280 x 720 (HD - most common)
- 640 x 360 (Minimum size - not recommended)
What is 16:9 Ratio?
This is the shape of the thumbnail. It means:
- For every 16 units of width, there are 9 units of height
- It looks like a rectangle lying on its side
- The same shape as most TVs and computer screens
File Size Rules
Besides the picture size, YouTube also has rules about file size:
- Must be under 2MB (megabytes)
- Can be JPG, PNG, or GIF format
- PNG gives better quality but bigger file size
- JPG is good for most thumbnails
