What’s on the Arches, Vaults and Domes poster
A definition and 6 facts worth remembering.
An arch turns a span into pure compression by curving. The price is a horizontal thrust at each springing, which something else has to resist.
- Masonry arches carry compression, not tension.
- The thrust line must stay inside the arch section.
- A flatter arch pushes outward harder.
- Buttresses, walls or ties take that thrust.
- A dome adds hoop tension near its base.
- Chains were added to the Pantheon and St Peter's domes.

- Who is the Arches, Vaults and Domes poster for?
- Arches, Vaults and Domes belongs to the Architecture section rather than to a school year, because design is not something one grade owns. Anyone learning structure can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Arches, Vaults and Domes poster?
- Use it on any masonry building, and when a client asks for a vault over a wide room. A wall chart earns its place by being glanceable from where the work is happening, so Arches, Vaults and Domes belongs on the wall where that design work actually happens, within glancing distance, rather than filed away.
- What other posters go with Arches, Vaults and Domes?
- How a Beam Works, Cantilevers and Compression and Tension sit alongside Arches, Vaults and Domes in the Architecture section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.How a Beam WorksCantileversCompression and Tension
- Is the Arches, Vaults and Domes poster free to download and print?
- Yes. Arches, Vaults and Domes 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 Arches, Vaults and Domes poster print at?
- Arches, Vaults and Domes 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 Arches, Vaults and Domes loses nothing.Printing guide
