Does anyone know how many studs this thing is in length and width? (just the regular flat one) I might be blind but bricklink had pretty vague info, and I've never owned one in the flesh. However I do have a bley one in the mail and need to prepare for its place in a gold mine moc, so any info out there would be greatly appreciated so I can get moving on that :)

Oveall it is 14 x 14. The 1x2 attatchment points are 13 x 13.

Thank you so much! Perfect image
