Fits a 13 inch MacBook Pro with a bit of room at the top where the opening is, maybe an inch or 2? .

Final Measurements (without anything inside) 13 inches x 8 inches. If you don’t want this stretchy I recommend using a cotton yarn, or a smaller weight yarn, but check your fit as you crochet by sliding it over your computer once you finish your starting chain.

Mine is stretchy so it could fit a larger one if wanted (I stuck my partners 15 inch gaming laptop and it fit just fine, but much larger would be a little tough and you might want to make your starting chain a little bigger. Just chain until it fits snugly around the width of your laptop and then follow the pattern as written. The stitch counts won’t match, but that’s okay.) and I fold the extra over to “close” it when I stick it in my bag, but if you want it a little more snug just decrease the amount of repeats you’re doing and it will shorten it down a bit. You could probably find a few buttons or even sew a zipper onto it, but I only had magnets and I feel like magnets vs a computer was a bad idea. I may add a zipper once I get my sewing machine though, or I’ll crochet it on at a later date and update here with how I did it. We will see.
