A0 Plotters: The 36-Inch Class in Metric

No. A0 is 841 mm wide, and a 24-inch machine runs a 610 mm roll — it physically cannot feed a sheet that wide. A 24-inch plotter tops out at ISO A1 (594×841 mm), ANSI D and ARCH D. If you need full A0, you need the 36-inch (914 mm) class. There is no driver setting or workaround that changes the roll width.

At least 841 mm, which puts you in the 36-inch (914 mm) class. The 914 mm roll carries the 841 mm A0 sheet with roughly 36 mm of total width to spare — enough for a full-bleed image and a clean trim on a poster, and comfortable margin on a plain drawing. Don’t jump to 44-inch or wider for standard A0; that width belongs to graphics and production work.

They’re close kin, not identical. ISO A0 is 841×1189 mm (33.1×46.8 in). ARCH E is 36×48 in and ANSI E is 34×44 in. All three are the largest standard sheet in their family, and all three need the same 36-inch machine to print. If your firm works to ISO you’ll set the sheet to A0; a North American shop sets it to ARCH E. The plotter doesn’t care — it’s the same 914 mm roll either way.

For AEC work, pigment. It resists water and UV, so the archival copy in the project file survives handling and light — that’s why it’s the default for drawings and tender sets. Dye ink is vivid and lower cost but fades faster, which matters for anything that hangs on a wall for months. Most modern 36-inch machines, CAD and graphics alike, run pigment now.

Only if you scan and copy wide-format documents. The wide-format MFP class adds an integrated scanner for print, scan and copy — useful for plan rooms, as-built markups and archiving old drawings. If you only print from digital files (CAD, BIM, PDF), a plain 36-inch printer is lighter, cheaper and one less thing to service. Buy the scanner when your workflow actually includes paper originals, not because it’s on the options list.

Dual roll if you switch media or sizes during a run. It holds two rolls at once — say bond and gloss, or two sizes — and switches automatically, so you don’t stop to reload mid-deadline. If you print one media type on one size all day, single roll is fine and cheaper. The dual-roll payoff shows up in mixed sets and in offices that run drawings and panels off the same machine.

Probably not an A0 machine. If your everyday work is A1 and D-size with a rare oversize sheet, a 24-inch A1 plotter plus outsourcing the occasional A0 to a repro shop is usually cheaper and simpler than owning a 36-inch machine that idles. Buy the bigger class only when A0 is routine. If you’re on the line, tell us your real volume and we’ll size it honestly.

The 36-inch graphics/photo class, not a CAD plotter. Posters and panels are judged on color gamut, smooth gradients and media range — matte, gloss, photo, canvas — which is a different tuning than crisp linework on bond. Shop the graphics leaderboard on this site rather than the CAD list. If you print both drawings and panels, a dual-roll machine or a color-capable 36-inch can bridge, but check the color grades first.

When the machine runs all day for more than one team. Clear signals: multi-set runs daily, a shared print room, or repro-shop duty where the plotter never cools down. Production and PageWide print-bar machines hold a pace a scanning inkjet head can’t, and they handle stacking and collation for large sets. Below that — even solid daily A0 volume — a dual-roll 36-inch is the right tool.

Yes. Technical machines print crisp linework on plain bond, which is what tender sets and GA drawings need — cheap, fast, readable. Coated and gloss media hold color and detail far better for posters and renderings, but cost more and run slower. That’s why the media you print on drives the machine you buy: bond-heavy linework points to CAD class, coated-media color points to graphics class.
