Google "what style windows for colonial house " you will get all the ideas you need IMO if you are trying to make yourhome more modern farmhouse then go the 4 x4 if not stick to the traditional window grid pattern

Context is key. What size windows? What does the house actually look like? What type of grids, internal grids, simulated divided, exterior only, interior only removeable?

Photos of the house needed.

"Colonial" means many things, some of them not 18th century, when glass was handblown and couldn't be made into big sheets.
