Sizing to 8*10

What aspect ratio gets you 8 by 10? Thanks

8 / 10 = 0.8

Thank you. Wh
en I move the aspect ratio "button" it goes up quickly . How do you get it exactly on .8? Thanks again!!!!

Use keyboard arrow keys (right/left) to fine tune the value.

Thank you for your patience. I hit .8, then visualize, and still not printing 8* 10.
Any other suggestions? I really appreciate your assistance.

Once you hit visualize export your cloud in PNG format (in Grab and Share section) and then print it as any other image or picture.
