Are the blocks 2 times smaller for retina than they should be?

Question

css

Hello. Such a problem. On retina screens, specifically on macbook 13', the blocks are small. It seems to be less than 2 times.
I write in css for retina:

@media (orientation:landscape) and (min-resolution: 113dpi) { }

Won't help. Please tell me how to fix.
Without the use of viewport needs to be settled.
