I was wonderring if anyone new how to enlarge a plan in 1/16th inch=1 foot to HO scale. I was hoping to use my copy machine but haven’t figured out the percentage to enlarge. Maybe someone has a better way?!?

Thanks, Rich

1/16 inch = 1/192 foot. So the scale of the drawing is 1:192. You want it to be 1:87 (HO scale).

192 / 87 = 2.207 or 220.7 % or 221%.

Enlarge your plans by 220 or 221% and you will have HO plans.
