I find it useful to have half an inch of overlap between panels to make it easy to line up the maps. I go with 0.5 inch margins to make life easy.

On the next page pick your paper format (remember, US letter and A4 are not the same), orientation and margins.

Note that there seems to be a bug between Photoshop CS5 output and posterazor which causes posterazor to get the dpi wrong, but we can deal with that later.

Check that the dpi setting in the Image Information is the same as the number of pixels in a single grid square (as we discussed on Monday).

There are a couple of ways of doing this, but I’m going to walk through the process using a great little free program called posterazor. So you may have a map that’s bigger than one page, and you want to print it off at home. However, a lot of maps from pdfs, such as Dungeon adventures, or from Paizo adventure paths, are sharp enough that with a little rescaling they can be easily dropped into a gaming session. It’s still sharp enough for most vtt uses – though it’s almost certainly too blurry for printing out at home. I took an extreme example here – the map from Wizards (by Mike Schley ) is very pretty, but it’s a very low resolution preview. I’ll be talking about using a nice little free program to slice up a large map for home printing tomorrow. Or you can print it off at 100% (turn off page scaling) and you should have nice 1 inch squares for your minis! It’s likely that your new scales up map will be too big to fit on one page. Throw this into your virtual tabletop of choice and you should now be able to lay in a 100px grid and have it all line up.Set the x and y resolution first, and then set width and height in percent. Click okay, and your image will scale up. First set the dpi to 100dpi – this will make the image print at 1 grid square = 1 inch – and then pick Percent from the drop down menu beside the Width field and enter your percentage – in this case 463%. That means I need to scale it up by 100/21.6=463% (you always scale up by a factor equal to /). That means the current image is 21.6/100 = 21.6% the size I want it to be. I want to scale the map up so that each square is 100px wide. In this case Photoshop tells me it’s 216 pixels for 10 squares (in the bar at the top of the window) and Gimp agrees (in the bar at the bottom of the window). Your program should now tell you the number of pixels in the 10 squares. I tend to measure 10 squares this way, as it makes the calculation easy.

Click one of the grid intersections and drag to another grid intersection on the same horizontal or vertical line.

In Gimp it’s just called the Measure Tool (shift-M to quick select). Click and hold the eyedropper and it will open up a set of tools. In Photoshop it hides underneath the eyedropper in the tools pallet.

Open up the file and select the measurement tool.

The following works well in both Photoshop and Gimp, but can also be used just as easily in most other graphics programs: How do you resize this so it can work in your home game? This map is 21.6 pixels per grid square – the wrong size for printing at home, and the wrong size for most virtual tabletops. Take this one from Wizards as an example. Many maps are provided at the wrong scale for a home game.
