Once you know the number of dots per square on your map image, scale the image so its dots-per-inch and matches its dots-per- square.
Multiply this result by 5 to get the width of each square in pixels. The result is the width of each square in pixels.Įxample: If you measured 330 pixels between grid lines 6 squares apart, then each square is 55 pixels wide.ĭivide the measurement in pixels by the number of feet. If in step 2…ĭivide the measurement in pixels by the number of squares. Result: The distance in pixels appears at the bottom of the window.Ĭalculate the width of a square in pixels. When you measure a vertical or horizontal separation, drag a 0° or 90° line. Measure the shortest line between your landmarks.Ĭlick one landmark, press and hold the right mouse button, and then drag to the second landmark.Īs you drag, the angle of your line appears at the bottom of the window.
Look for features that can establish a scale.Įxample: If the map includes 10-foot wide halls, the distance between walls can serve as a scale.Įstimate a distance between two landmarks that suits play. Pick two parallel grid lines far apart on the map. To measure the dots-per-square on a map image, do the following: 1įind two landmarks or marks on the map where you know the distance separating them. Measuring the dots-per-square on a map image For now, this procedure refers to 5-foot plots on your map as squares, even if the lines don’t appear yet.

Note: If your map image lacks a grid, I’ll explain how to add one in Adding a grid to a map image. Start by measuring how many dots now span a square on your map. To print your map image so each square spans 1-inch, adjust its scale so the image’s dots-per-inch matches its number of dots-per- square. In the Open Image dialog box, select the graphic file that will become the backdrop for your battle map, and then click Open.īattle maps in Dungeons & Dragons and Pathfinder feature a grid of 1-inch squares. To open your map graphic in GIMP, do the following: 1 PosteRazor splits graphic files too big for a single page into multiple, printable pages, which you can assemble into a poster-sized map. GIMP provides an image editor similar to Adobe Photoshop.

You must have the free programs GIMP and PosteRazor installed on your PC. Splitting a graphic file too big for a single page into multiple, tiled pages.Measuring the dots-per-square on a map image.This post includes the following sub-procedures: This post gives procedures for scaling graphic map files so they appear with a 1-inch grid, and then printing the map tiled onto multiple pages. Even when you solve the scaling, the images can’t fit on a single page from your printer. But these computer graphics never come scaled so that they print with a 1-inch grid sized for miniatures. Many of the artists who draw maps for adventures sell downloadable images of those maps. You can play Dungeons & Dragons and Pathfinder battles on a sketch, playing on a colorful, printed map raises your game’s visual appeal.
