Ok so i want to change my white pickup covers to black ones but i'm confused on where i should start measuring.

I think it's the top one but i'm just checking to be safe.

If you go here you'll get what i mean.

Thank you very much!
Neither. You measure from the middle of the poles; 1st string to 6th string.

However, with single coils like that, there are indeed far less spacing issues than you get with humbuckers and covers are almost always only sold in packs of three sized to match the bridge, middle and neck pickups. I don't think I've ever seen packs of single coils covers sold with only 50mm or 52mm spacing included, it's almost always one 52mm and two 50mm covers.
Yes, I know everything. No, I can't play worth a damn.
