Newbie. Simple Box - Jonyskids - 11-13-2019

I am trying to make a template. 

I need a canvas of 2.6875" x 3.21875", I nailed it no problem

But then I need a box the creates a border that is 39" thick or 2.2975" x 2.82875"

I can not seem to define this box by these measurements.

Any help is appreciated and apologize for the simple question.

The first thing to understand is that Gimp (and all bitmap editors) work in pixels, not inches. Only whole pixels, there cannot be fractions of a pixel. If you specify a size in inches the resolution you specified (dpi) is used to calculate the size in pixels. This is rounded to nearest whole pixel size. This creates a small variation in the inch size that you initially specified.

I don't understand this part.

OK, I think this is what you mean:
2.6875 - (2 x 0.39) = 1.9075
3.21875 - (2 x 0.39) = 2.43875

I created a new image size 2.6875" x 3.21875", 300dpi.

I then created a rectangular selection as per the image below.
Click inside the selection to finalize.
Bucket fill with colour you require.

Note: you will still get small variations in inch sizes when rounding to the nearest whole pixel takes place.

Thank you so much. You did indeed catch my mistake by adding the multiple of 2. I was also struggling because I had aspect ratio set to fixed.

Thank you.
