Easy to use app that quickly calculates border sizes for picture framing mats. Simply enter the size of your artwork or photography, the size of the frame it’s going into and the app does the math and shows you the necessary border sizes to perfectly center the artwork. Can be used with inches or metric, or even in decimal. Can also convert a single mat into a double mat with instruction on how to complete it. Includes links to dozens of helpful matting and framing videos plus a “where to buy” button to find ways to buy Logan products.

Full bleed assumption in border calc

The border calc assumes full bleed artwork equal to frame size & adds 1/2" to the border size. Cutting a mat to the calculated borders will hide 1/2 of the artwork on all 4 sides.

To have an assumption built into the calculator is just plain bad and extremely annoying. It needs to not be there. The frame size is the frame size & the viewable area of the artwork is just that too. Leave it up to us to input real numbers.

Other than that little quirk that was not documented & drove me nuts until Logan explained it, I like the idea of the app.

No options

I used this app once about September ‘17 and suggested improvements to Logan immediately. They indicated there would be improvements after the start of the new year but nothing so far. The problem is that the app simplistically assumes the mat will overlap the artwork by ¼” on each side - you don’t need a special app for that. My suggestion was to allow the user to specify the overlap on each side individually so that the overlap can be related to the artwork details.

Will not calculate

I have entered the dimensions many times and the calculator keeps moving my dimensions to overlay the instructions. Then it tells me to enter the dimensions. If it would just keep the numbers where I put them, perhaps I could get to the next step. Not helpful at all.
