One nice feature of Manga Studio 51 is being able to have your screen reflect actual real-world measurements. This is handy for checking margins and other things like output sizes. So let’s find out how.

For Apple laptops and displays, it’s on their support page. For my older MacBook the screen specs are right at the top of the page.

In the Display Preference panel, there are four screen resolutions to choose from:

The 1280 size is okay, but it’s a bit cramped for drawing. I prefer the 1440 size.

Regardless of which size I use, Manga Studio needs a dots per inch (DPI) setting for the screen. It’s easy to figure out, and will be much more accurate than using a ruler on the screen.

For the calculations below, I’ll refer to the hardware resolution as PPI and the Manga Studio setting as DPI.

Some quick math will get us the right setting. First we divide the scaled pixel width by the native pixel width. Then multiply the result by the native PPI to give us the scaled DPI.

Rounding to the one decimal place that Manga Studio 5 uses gives us the following:

For 1680 x 1050 use 149.0 DPI

For 1440 x 900 use 127.7 DPI

For 1280 x 800 use 113.5 DPI

For 1024 x 640 use 90.8 DPI

Now that we have our numbers we can setup Manga Studio 5 to show us the actual size on our screen.

Open your MS5 preferences to “Canvas”,

If your hardware manufacturer provides these specs, finding the DPI is easy. Otherwise, you might have to go old-school and hold a ruler up to the screen. That what I had to do with an old external monitor when I couldn’t find it’s PPI spec.
