What Size Is a YouTube Thumbnail

Before we get into the details of what YouTube users will deem as a clickable, attractive YouTube thumbnail, we must tackle the basics first.
Thumbnail dimensions, size, aspect ratio, and format are simple technical aspects you should get right every time you post a video on your YouTube channel. Not complying with the specific dimensions of thumbnail blocks any chance your target audience will get to view your content.
Get these specifications right on your YouTube thumbnail size, and you will at least be sure potential viewers understand what your YouTube video is all about in one glance:
- Minimum width – The recommended minimum width of a YouTube thumbnail is 640 pixels. If your thumbnail width is less than 640 pixels, YouTube will not allow you to post it as a video thumbnail.
- Aspect ratio – Images you use as YouTube thumbnails must have an aspect ratio of 16:9. This number means your image is 16 units long and nine wide, which is what YouTube uses to play previews.
If your aspect ratio is not 16:9, your videos will not have previews, and you miss out on the potential views your videos should be getting. Photoshop YouTube thumbnail size details to meet YouTube’s exact thumbnail specs, and you’re good to go.
- Max file size – YouTube will not allow you to upload a pic that has a file size larger than 2 Mb. You can go smaller, but we recommend using the 2 Mb for maximum clarity.
Some Tips on How to Add a Custom YouTube Thumbnail to Your Video

Here are some tips on making great-looking YouTube thumbnails that will ensure your YouTube videos will get the click-throughs and views you are counting on. Follow these tips for a more professional-looking YouTube channel:

YouTube Thumbnail Ideas

We have compiled a few ideas that you can easily incorporate into making your YouTube thumbnails more compelling.
Use good contrast visuals
Use color combinations that stand out well against each other. Prioritize visuals that are easy on the eyes. Avoid using complex visuals that are not readily understandable at a glance.
Keep fonts and design language consistent
Pick only one or two color themes. Compose your thumbnail pictures with only one design style. Use only one font type.
Let your thumbnails reflect your YouTube channel’s brand with a consistent look and feel and be more recognizable to everyone on YouTube.
Consider what imagery your target audience wants to see
Your potential subscribers prefer what they love. And if you use imagery that they are naturally attracted to, you assure your YouTube channel evokes the curiosity of people you want as followers.
Try to be different
A lot of YouTubers have similarly styled thumbnails. Stand out from the crowd and use a thumbnail style and composition that is your own.
Take your time in developing this style, but once you have a solid grasp of your look and feel, stick with it. Remember that your goal is to be readily recognizable to your audience at just a glance.
Thumbnails are Your Headlines

Being a YouTuber is a creative endeavor. Apply the same level of creativity to your thumbnails as you do with making content and reap the benefits of connecting with your target audience. Thumbnails are your headlines to potential viewers. Convert these potential viewers to subscribers and grow your YouTube channel to the next level.
