Sorry if this is the wrong place for this.
I'm currently trying to make a conworld map. If any of you are making a map, you can use this latitude and longitude grid I made. It is 1600x800 pixels, so that means it's in the equirectangular projection. If your conworld's size is similar to earth's, each pixel is about 10.02km2 (on the equator at least.)
I also made lines for 45°N and 45°S.
