Diamond Frame

Picture mats, planned on the phone

Privacy

See the opening before the board is cut.

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.

A shelf for the mats you care about

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.

Named projects

Give each mat a name and a short note, so the reason for a border is still there later.

Favorites

Star a project or a catalog size and spot it again without hunting.

A blank start

Begin from an empty mat when none of the saved ones fit the print in front of you.

Sizes people already know

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.

4 × 6 5 × 7 8 × 10 11 × 14 16 × 20 18 × 24 24 × 36 A5 A4 A3 A2 12 × 12 20 × 20

Borders with a little judgment

Equal, or deliberately not

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.

Proportions you can lock

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.

One window, or a small group

Choose how the mat is divided, then set the gap between openings when there is more than one.

Single One centered opening

A single window for a print, a photograph, or a certificate.

Double stack Two openings, one above the other

A shared gap between a pair of stacked windows.

Triple row Three openings in a line

A row for a triptych, with the same gap between each window.

A sheet you can hand over

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.

Inches, millimeters, and a quieter screen

Inch or millimeter

Switch the unit system. The project you have open converts with it.

A default border

Set the border width new mats start from, including the bottom-weighted choice.

Light, dark, or system

Match the phone, or keep Diamond Frame in a light or dark look.

On the home screen

A widget shows your latest project, or a favorite size, and opens Diamond Frame when you tap it.

Frequently asked questions

What is Diamond Frame for?

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.

Can I keep more than one mat?

Yes. The shelf holds your projects. You can rename one, duplicate it, mark a favorite, add a note, or delete it.

Are everyday frame sizes included?

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.

Can the mat have more than one opening?

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.

Will my projects stay on this phone?

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.

Does Diamond Frame require a subscription?

No subscription or in-app purchase is required.

Who do I write if something feels unclear?
