Hello I have a rather interesting problem with the quad-fold template measuring 18 x 18" and 5475 pixels x 5475 pixels.
If I wanted to make a game with 1inch x 1inch squares, I could theoretically fit 18 x 18 of them on the quad-fold board.
But, I want to make a game with 1.35 inch squares. So I have tried to work out how many pixels are in a 1.35 inch square.
Three separate inch to pixel converters online insist 1.35 inches is 129.6 px. Ok, so far so good, but now it gets problematic.
If I ask these same converters how large 18 inches is in pixels they all tell me, 1728 pixels.
But my quad-fold template is 5475 pixels yet also insists it is 18 inches.
If I subdivide 5475 by 129.6 I get approximately 41. So, the math is telling me that I should be able to get forty-one x 129.6 squares across the quad-fold board.
Remembering that 129.6 is MORE than an inch, and equates to 1.35 inches, somehow, I am getting 41 squares each larger than an inch, across an 18 inch board.
Can someone help me figure out that I'm either stupid, or something is not adding up with the figures given for the quad-fold board? Thank you.
There is no single universal conversion between pixels and inches. Pixels per inch is a setting you can set to be whatever you want. The online converters were using a setting of 96 pixels per inch.
However, TGC requires all files to be 300 pixels per inch.
The quad fold board is 18"x18", but it also has a 1/8" bleed all around it. So the template is actually 18.25" x 18.25".
If you take 18.25 (inches) and multiply it by 300 (pixels per inch), you get 5475 (pixels), which is the size of the template.
If you want your square to be 1.35", they would have to be 1.35x300 = 405 pixels.
Hope that makes sense.
