+## Sizes 
+PADD will display on screens that anywhere from 20x10 characters to over 80x26 characters.
+
+As your screen gets smaller, you’ll be presented with less information… however, you’ll always get the most important details:
+- The status of your Pi-hole (is it online, in need of an update?),
+- How many ads have been blocked,
+- Your hostname and IP, and
+- Your CPU’s current load.
+
+It will also run in the following modes (shown further below):
+- Pico: 20x10 characters
+- Nano: 24x12 characters
+- Micro: 30x16 characters
+- Mini: 40x18 characters
+- Tiny: 53x20 characters
+- Slim: 60x21 characters
+- Regular: 60x22 characters (takes up the entire screen on a 3.5" Adafruit PiTFT using the Terminal font at 8x14.)
+- Mega: 80x26 characters
+
+### Sizing Your PADD
+How PADD will display on your screen depends on the size of the screen in *characters*, not *pixels*! PADD doesn’t care if it is running on a 5k Retina display on your $5,000 iMac Pro or on a $5 display you bought on eBay.
+
+If you want to change how PADD displays on a small display attached to your Raspberry Pi, use
+```bash
+sudo dpkg-reconfigure console-setup
+```
+to configure your font settings to an ideal size for you.
+
+If you want to change how PADD displays through a terminal emulator (PuTTY, Terminal.app, iTerm2, etc.), resize your window or play with font sizes in your app of choice.
