the 7.5-minute USGS maps are designed to be printed at 1:24,000. If I compress the image in order to fit more topographic information on a single page, the contour intervals and writing become illegible - in the specific case of USGS maps, beyond about 1:30,000. I use the original map’s native scale, e.g. When using smaller paper sizes like 8.5 x 11, I struggle to understand the big-picture topography and I get annoyed by how often my route cuts across pages.

Tabloid sheets depict a sizeable area (about 4.5 miles tall and 3.2 miles across when printed at 1:24,000 scale with quarter-inch margins) while still being field-friendly (not too big) and a standard paper size (not requiring a super high-end printer). I prefer Tabloid (11 x 17 inches) paper over smaller sizes like Letter (8.5 x 11). But until these platforms are available deep in the backcountry on devices that don’t break or need recharging, as part of my trip planning routine I export and then print my digital maps into a field-friendly paper set. Today we’re fortunate to have excellent online mapping platforms like CalTopo, Hillmap, GaiaGPS, and AllTrails.
