Slider images all different sizes


I am very new to Wordpress and to blogging and am having trouble with image sizes and the slider on my site. When I upload my images to Wordpress I resize them so they are all the same size, and they all appear to be the same size on Wordpress when I view my posts, but for some reason when I open image details they are all different sizes. So the largest photo (4272 x 2856) appears as a banner across the screen which is what I want, but other images that are somehow smaller (1920 x 1282) appear as smaller squares and don’t extend across the screen.

I am not sure why this is happening or why the images are different sizes when I open them as I resized them all to be the same and they all appear equal on my screen.

I deactivated all my plug ins and it didn’t fix the issue, and I tried to resize the smaller photos in Wordpress and that also didn’t help. Any help would be appreciated, thanks! My link is

Hi @emily86,

I hope you are well today and thank you for your question.

Please try regenerating thumbnails on your site using the below plugin.

If you still face the issue then please share the screenshot of it.
