Who is the Density poster for?
Density belongs to the Architecture section rather than to a school year, because design is not something one grade owns. Anyone learning urban design can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Density poster?
Use it when someone argues that density means towers. It usually does not. A wall chart earns its place by being glanceable from where the work is happening, so Density belongs on the wall where that design work actually happens, within glancing distance, rather than filed away.
What other posters go with Density?
Housing Typologies, Active Frontage and Garden City sit alongside Density in the Architecture section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Housing TypologiesActive FrontageGarden City
Is the Density poster free to download and print?
Yes. Density downloads as a free PDF with no account, no email and no watermark, like everything else in the Architecture section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Density poster print at?
Density is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Density loses nothing.Printing guide
