We print three sizes, and they are the three sizes every frame shop stocks.
| Size | Inches | Ratio | Closest standard | Suits |
|---|---|---|---|---|
| 30×40 cm | 11.8×15.7 in | 3:4 | between A3 and A2 | one clean route, a shelf, a hallway, a gift that needs no rearranging |
| 50×70 cm | 19.7×27.6 in | 5:7 | an A2 sheet fits inside with a mount | the default: reads across a room, dense city routes still separate |
| 70×100 cm | 27.6×39.4 in | 7:10 | almost exactly B1 | long routes with structure, and every heatmap |
The data prints have sizes of their own: The Clock is 50×50 cm, The Curve is 30×40, the rest follow the motif's page.
Which size for which route
The route decides, not the wall. A point-to-point ride is a simple shape and reads at any size. A city marathon folds back on itself and needs 50×70 for the loops to separate. A heatmap of a season is hundreds of lines and needs the space between them, which is 70×100. What size should a route print be goes through it with examples; the short version is that a single run rarely needs the biggest sheet, and a year of them always does.
Not A2, not A1
A-series paper has a different shape from ours: 50×70 is wider than A2 (42×59.4 cm), and 70×100 is a little wider than A1 (59.4×84.1) and almost exactly B1 (70.7×100). That matters for one thing: a frame sold as "A2" will not take a 50×70 print. Buy the frame by the print's size, not by a letter. Frames covers what fits.
Framed sizes
A framed print has the same outer dimensions as the paper: a framed 50×70 is 50×70 cm on the wall. The frame's lip covers about 12 mm of the print's edge, which the layout allows for — the margin is generous, and nothing that matters sits in the outer centimetre. The print is not made bigger to compensate, so a framed print and a loose one in a shop frame end up the same size on the wall.
Print resolution
The print file is a vector PDF: the line, the text and the drawn maps are shapes at the sheet's physical size, not pixels, so there is nothing to enlarge and a 70×100 is as sharp as a 30×40. The one exception is the satellite background, which is a photograph: it is fetched for 300 dpi on the size you order, never below 150, and the editor tells you if a route is too small to print it sharp. The limit on a very large sheet is the recording, not the printer: past 70×100 you enlarge GPS wobble along with everything else. Every specification is on one page.
Paper and 70×100
70×100 is made on Museum 250 gsm only; the lighter sheet bends under its own width. The two other sizes come in both papers. Paper.
