@Bob_Ciolino thanks for the message!
The most common way to do this is to adjust your base tile size to be smaller and then increase the size of each of your ‘normal’ tiles accordingly.
Update: With the release of Scalable Dashboard layouts, this concept still applies, but rather than reducing the Tile Size setting, you would increase the number of columns per row.
The base tile size is Medium (160px). So if you wanted to be able to create ‘half’ sized tiles, you could change your baseline Tile Size in the Dashboard Settings to Tiny (80px) and then double the size of all your existing tiles to get them back to ‘normal’.
(eg. 1x1 tiles become 2x2… and 2x1 tiles become 4x2 tiles).
Here’s an example video where I reduce the base Tile Size by half so I can make the garage door tile 1/2 sized:
Note that you can also use a ‘Custom’ tile size which lets you specify any baseline tile size dimension you want. The thing to keep in mind is that the tile size in the Tile Editor is a multiplier of baseline tile size (literally 1×baseline, 2×baseline, etc.).
