The Ideal Thumbnail Size for YouTube & Best Practices

In recent times, the world is revolutionizing into quite a digital one.

From pursuing education online to even marketing your products and services on a digital platform, everything and anything is going virtual.

One such popular platform that receives the most traffic happens to be none other than YouTube.

Uploading videos on YouTube has been all the rage now, mainly because of how flexible and diverse the platform is. The audience base is also varied, so all kinds of talents and content is appreciated on YouTube. 

However, the most important part of uploading any video on YouTube is the thumbnail.

A thumbnail is what will first attract your audience to click on your videos which later will generate views and likes. 

Clickbait Thumbnails

Setting the ideal thumbnail size for YouTube can be a really tricky job. Unfortunately, most people on YouTube these days use a lot of “click-bait” thumbnails.

Click-bait thumbnails are used to make sure the videos generate the highest number of views as their flashy and unique appearance prompts people to click on them. 

The thumbnail of these click-baited videos usually have no correlation to the content inside. As a result, the highest traffic it can gain is only through views and not “likes” or “subscriptions”. 

If you are a content creator on YouTube, the first thing you should do is make a thumbnail for your videos, however, the thumbnail should be honest and true to the content inside. 

As flashy and fun as many click-bait thumbnails may seem, it is best to simply stay away from using such concepts yourself. Yes, you might be generating a lot of views for that specific video, but you will only be contributing to more damage in the long term.

Your audience will slowly move away from watching your videos as they might be deemed as fake and merely a sham. 

Ideal Thumbnail Size for YouTube

Thanks to many amazing websites on the internet, you can now easily create custom thumbnails with only a few clicks.

When it comes choosing YouTube thumbnails dimensions, know that YouTube typically allows a thumbnail image format of about 1280 pixels in width and 720 pixels in height

Try not to go for a format bigger or smaller than this as the image may get distorted due to over-stretching or the opposite.

On the other hand, the original thumbnail size for YouTube itself should be of only 640 pixels, with a ratio of approximately 16:9 only. 

In case of the aspect ratio, 16:9 is ideal as it gives your image the perfect room to be stretched or constricted into a thumbnail, while also maintaining its original quality. 

Thumbnail Size for YouTube

One of the silliest mistake people make is using either an over-large or super small image for their thumbnail. If you are going for the custom thumbnail route, we would suggest you to stick to the basic thumbnail size of about 1.5 megabytes.

Try not to go over this size as it could be rejected by YouTube’s algorithm and rules. 

The format of the file should also be either in PNG, JPG, GIF, or BMP. As we mentioned before, the resolution of the image should also not be under 1280 x 720. 

When it comes to the ratio, stick to approximately 16:9 only. YouTube videos usually follow this aspect ratio as it allows the content to be played on most players and previews.
