WordPress Gallery Thumbnail images look blurry

luckily I found the answer shortly after posting this question. My thumbnail size setting (Settings/Media) was 150 x 150px – cropped.

So when I displayed them on my page, desktop size, in a row of 4, the thumbnails were getting stretched to 282 x 282px.

I changed it to this new size and used a Rebuild Thumbnail plugin and it looks great now. It scales down nicely so just set it to the maximum size it will be on desktop and it’ll display flawlessly.

Cheers
