Armor plate sizes?

[Witchgrass]

I bought a Condor tactical vest for Crossfit training purposes, and to wear around the house to impress the wife. Instead of buying Rogue Plates At $80, I figured Could make my own. Does anybody know the dimensions for the front and rear plates? A skematic, maybe? According to Rogue, the plates are around 8.5 pounds each, along with the vest for a total of 20 pounds.
Anyway, thanks for any info you can give.

They vary slightly depending on cut/style but the ones i have are 10 in wide by 12 in tall. Exact dimension is more like 9.75 x 11.75.

Ok, this get me pretty close. I’m thinking I will need to go with 5/16” plate, and start cutting it down till I get the correct weight.
