Fenders size

Hi everybody, rain and autumn is coming strong where I live so I’ve been looking to install fenders on my commuter (sks bluemels).

I’m running maxxis DTH 26"x2.3 on my bike, any of you have idea which size I should get to have them fit tight as in the pictures attached ? I know it’s not ideal but I’m only riding my bike on clean city concrete like the look a lot (Pics aren’t mine btw)

Also, do you guys have any mud flaps references you could recommend to attach on the bluemels ? I find these super cool but have no ideas where to look at for these !

Thanks a lot for your help guys !
