This is a sheet to sketch a plan on rather than general graph paper. Pick a scale and the grid is drawn to it: at 1/4 inch = 1 foot each square is one foot, with a heavier line every four; at 1/8 inch the squares are still a foot with a heavier line every eight; at 1:50 each square is half a metre with a heavier line every metre. US Letter landscape at quarter-inch scale covers 40 feet by 30 feet of plan, which is a generous floor of a house.
Along the bottom left a graphic scale bar is printed in the usual alternating black and white segments, labelled in feet or metres. It is drawn from the same grid unit as the squares, so it is correct by construction, and it stays correct if the page is photocopied or scanned at a different size - which is exactly why drawings carry scale bars rather than only a ratio. A heavy frame runs round the whole sheet.
In the bottom right corner sits a title block aligned to the grid, with rows for PROJECT, DRAWN BY, DATE, SCALE and SHEET. The scale row is already printed with the scale you chose; the other four are fillable form fields, so you can type a project name and a sheet number before printing a set. One landscape page in US Letter or A4.
