Size of pictures in Horizontal format

Hello,

All my pictures mesures 800px in the larger side.

However, when I upload my pictures in a gallery in horizontal format, they have not exactly the same size.

They alternate between little larger and and little smaller :

Can I change this somewhere ?

Thank you !
