▣MAT & MOULDINGBENCH / WORKSHOP PLANNER
● Local-first v1.0

PRECISION BEFORE THE FIRST CUT

A clear plan.
A better framing day.

From artwork to mat windows, mitred moulding and a printable work card. Keep every measurement on the same bench.

EXAMPLE DATASynthetic job · separate example storage

Example measurements and prices are synthetic. Start a real job to use your shop’s materials.

01

Artwork & mat

Dimensions on the finished front face

Artwork size

Use decimal inches or fractions such as 8 1/2. Millimetres use decimals. Values are stored at 0.001 mm precision.

Overlap on artwork per edge

The lower opening is artwork minus the overlaps. Defaults cover 1/4 in on each edge; adjust to the image and mounting method.

Mat borders blank edge → lower opening

02

Moulding & stock

45° mitres · standard rectangular profile

Read the three length rules

Rabbet-line length = blank size + total fitting clearance. Sight / short-point length = rabbet line − 2 × lip. Outside / long-point length = sight + 2 × face width.

Face width is the full front width from the sight edge to the outer edge. Rabbet lip is the horizontal distance from the sight edge to the back rabbet wall, not rabbet depth. Never substitute an outside, sight or rabbet measurement for another. Confirm your saw stop’s reference edge with a test cut.

Allocation reserves both end trims and one axial kerf allowance per piece. It uses outside long points, with no shared-mitre nesting. Greedy allocation is conservative and does not guarantee a mathematical optimum.

03

Materials & bench time

Your rates · area estimates, not supplier quotes

Board and glazing costs use full rectangular blanks; no deduction for windows. Moulding uses whole allocated sticks. No sheet yield, tax, markup or inventory valuation.

Colour blocks are schematic; no artwork is uploaded. Inspect aperture position and visible borders before cutting.

Cut & fit schedule

Cutting reference & limits

Window measurements are finished front apertures. Back-of-board pencil lines, bevel offsets, blade start/stop positions and overcut compensation depend on your cutter and board thickness. Calibrate on scrap. For a double mat, both blanks have the same outer size; the lower opening covers artwork and the top opening is larger by twice the reveal.

Clearance is the total added to each frame dimension, not per side. This preview centres the blank in that clearance; actual fitting can move within it. Check rabbet depth against the whole stack separately. This tool does not verify depth, conservation methods, warped stock or saw accuracy.

Stock allocation

Each piece is labelled by frame, width/height and side. Kerf is an axial allowance along the stick; measure it for your saw and cutting method.
