Your tileset resolution determines the size of the tiles. I think Hoder’s is one of the smallest ‘stock’ sets at 16x16.
HRose’s is 10x10 ( but incomplete and is ‘retro’) http://smf.cataclysmdda.com/index.php?topic=3901.0
Since the tiles are only 10 pixels by 10 pixels your 43 width and 93 height will not take up as much screen space. 62% less if you go from a 16x16 down to a 10x10. This means you will be able to increase your height and width within your desktop since the space those numbers represent are smaller.
Another explanation: at 93x43 you are multiplying 16x16 or 93x16 = 1488 and 43x16 = 688 === or 1488x688 window
93x43 multiply 10x10 == 930x430 pixel window so you can see you can increase the number of tiles on this one since it will take up less pixel real estate, you lose some fidelity, though
For font to work you have to use the ASCII or ‘curses’ version that is just letters and numbers. Just turn off tiles.
You can open the image file and re-size it, but remember to change the ratio in the .json file and make whatever you want smaller yourself.
