If you use any of the thumbnail views, the dimensions column cannot be enabled however, the tool tip method will still work.

Also, you must have the View option set to List. The downside, or rather a little annoyance with this method is that you have to enable the column for every single folder with images. This is much easier than the tool tip method since you don’t have to wait for the information to appear. The Dimensions column will show you, at all times, the dimensions of the image. This will add a Dimensions column to File Explorer for that folder only. Right-click the title of any one of the already enabled columns, and from the context menu, select ‘Dimensions’. This only works inside File Explorer so while it’s more reliable than the previous method, it won’t work on your desktop. It all depends on how much time you have. Sometimes you need to select, unselect, and select the file again to get the tool tip to appear. The problem with this method is that the tool tip doesn’t always show up. The tool tip tells you the type of file it is i.e., its file extension which is useful if you’ve hidden them, its dimensions, and its disk size. All you need to do is hover your mouse cursor over an image and wait for the tool tip to appear. This works inside File Explorer but also on your desktop. SPOILER ALERT: Scroll down and watch the video tutorial at the end of this article. If you need to view image dimensions in File Explorer, then there are two ways to go about it. This bar was incredibly helpful because it gave you quick details for any file, especially images. There are some minor changes though for one, the Properties bar that appeared at the bottom when you selected a file no longer exists. On Windows 7, it looked very different but most features that it had back then are still part of the app in Windows 10. File Explorer has gone through some changes in the past few years.
