Your image is already 16:9
Keep the original dimensions if you want to preserve the image at its current resolution. Or resize it to 1280 × 720 if you want a smaller, standard-sized thumbnail.

YOUTUBE THUMBNAIL SIZE
Your thumbnail has one job: look good and fit the upload limits.
YouTube thumbnails are recommended at a 16:9 aspect ratio. A common working size is 1280 × 720 pixels, but you may already have a larger image you want to keep.
The other headache is file size. If your thumbnail is too large, you need to compress it without turning it into a blurry mess.
WHAT SHOULD YOU CHOOSE?
It depends on the image you started with.
Your image is close to 16:9
Your image is slightly different from the 16:9 ratio. You can keep its original dimensions or resize it to 1280 × 720.
Your image isn't 16:9
Crop the image to fill a 16:9 thumbnail, or fit the entire image with padding. You choose what happens to your image.
THE 2 MB PROBLEM

Large images can look great but still be inconvenient to upload. Compression reduces the file size while keeping the image usable as a YouTube thumbnail.
