There's one paper here, and there's a reason for that. Every unframed print goes onto 250 gsm uncoated off-white archival stock, at A4, A3, A2, 50x70 cm and 70x100 cm. No gloss option, no lighter budget stock, no choice to get wrong.
Uncoated matters more than the weight does. There is no shine on it, so it reads as drawing paper rather than as a photograph, and it suits a pencil line or a flat block of colour. Off-white, not bright white, means the paper has a faint warmth to it, which stops a white-heavy image looking clinical and stops a dark one looking like a screenshot.

Which art styles suit aeroplane posters
Line work, above everything. The blueprint and the line drawing are the two treatments built out of flat colour and clean edges, and a matte uncoated sheet is the surface they were made for. Put either onto something glossy and you get reflections across exactly the lines you wanted people to follow. The vintage poster style sits happily here too, because flat saturated colour on matte paper is what a real printed poster was.
What it suits less is a photograph you want to punch. A sharp, contrasty shot of an airframe against a hard blue sky has more in it than matte paper can give back, and that is the argument for the metal print.
Aviation poster sizes: A4 to 70x100 cm
A4 and A3 are desk and shelf sizes, seen from a foot or two away, which is exactly where fine detail gets examined. A2 is the first size that'll hold a wall on its own. 50x70 cm and 70x100 cm are room-scale, and at that range they are far more forgiving of an imperfect source file than the small sizes are, because they are seen from across a room, not from a foot away.
Your photograph decides which of the five you are offered. The site measures the file against the physical print size and will not sell you one that falls under the resolution floor, so the list you see is already filtered to what your image can carry. Turning plane photos into wall art explains how that is worked out.
A vintage aviation poster from a modern photo

The vintage poster style redraws your photograph in flat, saturated colour with the fine detail simplified, in the manner of an old travel poster. It's a restyle of your own photo: you upload the shot, see a free watermarked preview, and the poster is printed from the version you approve. The aircraft keeps the shape it has in your photo, but its colours move into the poster palette and fine detail is simplified, so check the preview before you approve it. Aircraft art styles explained compares it with the blueprint and the line drawing.
Want it glazed and ready to hang instead? That is the framed print. The rest of the surfaces are on on the wall.
Order an aviation poster from your photo
To print the photograph as you took it, start the poster with your photo, and the page lists only the sizes your file can carry. To redraw it first as a blueprint, a line drawing or a vintage poster, choose an art style for the poster and see a free watermarked preview. Either way the photograph has to be yours, or one you have permission to reproduce.
