Version 0.28.181.39f introduced the ability to increase the grid from 80 tiles wide by 25 tiles high to as many as 200 by 200. The resolution and font are still a critical concern and must be calculated to match, to avoid strange results and crushed fonts.

Choosing a grid for a font and resolution combination

Choose a font, know your resolution
Determine your tile size.
- A tile is one character, with its background, as displayed on screen.
- For the font you've chosen, they are usually named for a target screen resolution, or are named for the tile size... given neither, you could determine based on the dimensions of the font image itself:
  - If the font name contains a large pair of numbers, it usually means the target resolution for 80 columns and 25 rows. Example: curses_800x600.bmp indicates that its tiles are 800/80 = 10 pixels wide and 600/25 = 24 pixels tall. In this particular case, the tiles are actually 12 pixels tall but look good when doubled to 24 pixels tall.
  - If the font name contains a small pair of numbers, it's usually the tile size. Most new tile sets use this, like Tahin_16x16_rounded.png indicating 16x16 tiles.
  - If you're not sure, you can examine the tileset image, which uses 16 rows and 16 columns of tiles. Simply divide each of the dimensions by 16 and you'll have your tile size. For example, if an image was 144x128, you'd have a 9x8 tileset.
Divide your screen resolution by your tile size to get your target grid, rounding down.
- Example: screen 1600x1200 and a 16x10 tile. 1600/16 = 100, the number of 16pixel tiles you can fit horizontally. 1200/10 = 120 10 pixel tall tiles you can fit vertically. For this example, you'd use a grid setting of [GRID:100:120]

Notes

The title screen will be situated in the top right of the screen, instead of centred.
Setting [TEXTURE_PARAM:LINEAR] instead of [TEXTURE_PARAM:NEAREST] will make squished tiles better looking.

Notable Combinations

[FULLSCREENX:1600], [FULLSCREENY:1200], [FONT:curses_640x300.bmp], [GRID:200:100] (640x300 is 8x12 per tile)
[FULLSCREENX:800], [FULLSCREENY:600], [FONT:curses_640x300.bmp], [GRID:100:50] (640x300 is 8x12 per tile)
[FULLSCREENX:1920], [FULLSCREENY:1200], [FONT:curses_800x600.bmp], [GRID:192:100] (800x600 utilized at 10x12 per tile, for an almost square aspect ratio with lots of view space)
[FULLSCREENX:1280], [FULLSCREENY:1024], [FONT:{any 16x16 font}], [GRID:80:64]
[FULLSCREENX:1680], [FULLSCREENY:1050], [FONT:{any 16x16 font}], [GRID:105:65]

Windowed combinations

[WINDOWEDX:1272], [WINDOWEDY:960], [FONT:curses_640x300.bmp], [GRID:160:80]

-'''To work out what grid size you want for a given screen resolution and font tile size:'''
+== Choosing a grid for a font and resolution combination ==
-# Determine your tile size. This may be found by dividing the x value of the intended screen resolution of the font by the x value of the grid, and then the y values are divided by each other. Example: If we use the default grid size, 80:25, and the resolution of curses_800x600.bmp, 800x600, then we would divide 800 by 80 to get 10 and 600 by 25 to get 24. This means our tiles are each 10x24. Note the tiles in curses_800x600.bmp are actually 10x12.
-# Divide the x value of your screen resolution by the x value of the tile size to determine your wanted x grid value, then do the same with the y values to determine your y grid value.
+# Choose a font, know your resolution
-# Change the [GRID] entry in the init.txt file to reflect your changes.
+# Determine your tile size.
-* Note: if your font is, for example, a 16x16 font, as specified in the filename, this means that each tile is intended to be 16x16 pixels in size, and you may therefore avoid the mathematics in step 1
