Do you guys look for images that are the exact resolution of your screen or bigger? Any image I download appears slightly blurry as wallpaper.

Definitely go bigger...much bigger. Custom wallpapers on iPads can be a bit tricky. I don't know which iPad you have, so I'll be referring to the dimensions of my 11" iPad Pro (1668x2388) to help explain why below.
  • Perspective zoom. If this is something you use, then you'll want an image larger than the dimensions of the display, otherwise the image will get stretched out so it can do the parallax effect. Images get blurry when they are stretched out. (I'm suspecting this is the main cause of your blurriness. You could turn perspective zoom off, and be sure to pinch to zoom out on the image when setting it as your wallpaper since it will be zoomed in slightly by default.)
  • iPad wallpapers rotate when the screen rotates. If I were to use an image with the exact resolution of 1668x2388, it'll look great in portrait mode (when perspective zoom is off). However, it'll be blurry in landscape mode because now it has to stretch the width of the image (1668px) to fit the width of the display in landscape mode (2388px). Again, stretched out images are blurry.
So putting these two together, if I want an image to look great on my iPad in both orientations, I would need an image of at least 2388x2388. That would be the bare minimum if I have perspective zoom turned off, and would need something even larger with it turned on. Just for reference, the dimensions of the stock wallpaper images for my iPad is 2864x2864.

Long story short, use a larger image. Images can be scaled down without losing much detail, but images cannot be scaled up and retain the same level of detail or crispness.

Perfect, thank you!
