What this template builds for you
Picture frames are the cheapest way to practice miters — $1–2 of scrap stock makes two or three frames. Inaccurate 45° miters show gaps in seconds, so they're the perfect drill for eye-and-hand precision.
Enter your print size (5×7, 8×10, A4, A3, etc.) and the template auto-computes outer frame dimensions, glass dimensions, and backer-board dimensions. Pick edge width (slim 2 cm Nordic / wide 5 cm classical), thickness (12 mm light / 18 mm substantial), and add a hanging-cord hole or kickstand.
Material cost per frame is $1–3, but frames hang on the wall and you see them every day. Build six matched frames, hang them on one wall with family photos, and that wall is uniquely yours. Once your miters are tight, every four-cornered piece you build — trays, boxes, drawer fronts — benefits from the same skill.
Who this template suits
✓ Recommended for
- · Beginners learning miter joinery
- · Gift projects
- · Custom-sized frames
× Not for
- · Frames larger than A1 (you'd need thicker stock to span)
- · People wanting a metal or aluminum-frame look (this is a wood template)
- · People who don't care about miter gaps (frame gaps are very visible and take practice to hide)

When you'd build one
Print a wedding photo, build a wooden frame, give it to the couple — beats anything off the IKEA shelf.
Build ten frames and the miter skill jumps visibly.
Family portrait blown up to A2? Store-bought frames don't exist at that size — fastest path is to build it.
Build six matched frames in the same wood and width, hang them on the entry wall with family photos — more meaningful than any decorative print.

FAQ
How do I get the 45° accurate?+
Set the table-saw blade to 45°, clamp a jig, push slowly. Beginners can start with a mitre box — easiest way in.
Where do I buy glass?+
A local glass shop will cut 2–3 mm float glass to your dimensions. UV-cut glass costs roughly 3× more if you care about UV.
Backer board: ventilation?+
Not needed, but it must open (to swap photos). The template uses turn-button catches (4 small latches).
What edge thickness?+
12 mm is light, great for small frames (5×7, 8×10). 18 mm carries presence for A4 and up. Too thin and miters have very little gluing area.
Where do I get turn-button catches?+
Any hardware store ($2 for a bag of 20). Chisel a shallow seat for them. Glue + filler also works, but turn buttons make swapping photos easy.
