For Interior Designers
Furniture-scale plans, 1/2" kitchen-and-bath grids, and oblique cabinet sketches.
Who this collection is for
Interior designers live at 1:20 and 1:50 - close enough to the room to feel the fixture dimensions, far enough back to see how the layout reads as a whole. The grids on this page give you accurate fixture-template scales, cabinet-elevation oblique grids, and the fine-grain detail rulings you need for tile and stone schedules without the visual heaviness of an architectural construction set. Recommended reading: A reading list of essential references can complement these grids.
Why curated grids matter
Every discipline reaches for a slightly different palette of printable paper. The wrong grid can quietly distort a sketch - too dense for the brief, too sparse for the detail, calibrated to a scale you don't actually use. This page gathers the 6 grids most-used by working for interior designers practitioners, with the standards and history behind each one. Read first: How to print at exactly 1:1 before printing anything that needs to be measured.
