Give each mat a name and a short note, so the reason for a border is still there later.
Picture mats, planned on the phone
Diamond Frame is a quiet studio for picture mats: name a project, set the borders, try a familiar size, and keep a sheet of measurements you can share.
Projects stay listed with their outer size and layout. Open one again, duplicate a layout you liked, mark a favorite, or remove what you no longer need. The first visit already includes a few starter mats.

Star a project or a catalog size and spot it again without hunting.
Begin from an empty mat when none of the saved ones fit the print in front of you.
The catalog holds common outer sizes from US print formats, ISO A-series sheets, and two squares. Search by name, narrow the list to US or ISO, and load a size straight into the work you have open.
Link all four borders so they stay even, or set them separately. A bottom-weighted option adds a slightly taller border along the lower edge, the way a hung picture often sits.
Keep the opening free, or lock it to 2:3, 4:5, 5:7, a square, or an A-series proportion. The preview updates as you move the borders.
Choose how the mat is divided, then set the gap between openings when there is more than one.
A single window for a print, a photograph, or a certificate.
A shared gap between a pair of stacked windows.
A row for a triptych, with the same gap between each window.
Generate a cut sheet for the project you are in: outer size, borders, each opening, and the rabbet allowance, written in inches or millimeters. Share that text through the share menu on your phone. If a change went too far, step backward and forward again before you save.
Switch the unit system. The project you have open converts with it.
Set the border width new mats start from, including the bottom-weighted choice.
Match the phone, or keep Diamond Frame in a light or dark look.
A widget shows your latest project, or a favorite size, and opens Diamond Frame when you tap it.
Planning a picture mat: the outer size, the openings, the borders, and a cut sheet you can read or share. It is a planning aid. Check important cuts with your own tools before you cut board or glass.
Yes. The shelf holds your projects. You can rename one, duplicate it, mark a favorite, add a note, or delete it.
Yes. You will find common US sizes, ISO sheets from A5 to A2, and square formats. Search or filter, then apply a size to the mat you are editing.
Yes. A single opening, two stacked openings, or three in a row. When there is more than one, you can set the gap between them.
Projects, size favorites, and unit choices are stored on the device. Sharing a cut sheet uses the share menu you choose. Clearing the app’s data in system settings removes what is stored locally.
