Changelog

This is where every notable change to FramingMath gets recorded — new calculators, new guides and fixes — most recent first. It's hand-maintained, so each entry marks a real update rather than an automated version bump. Jump straight to the multi-opening mat calculator or browse the framing & matting guides.

   Preview your art, plus two new mat calculators

   See your own photo inside the mat and frame before you cut, enlarge the preview to check it, and reach for two dedicated new calculators — one for double mats, one for bottom-weighted mats.

   • Double mat calculator — sizes the under-mat window, the larger top opening and the reveal, with an accent-color swatch
   • Bottom-weighted mat calculator — a wider bottom border by a fixed amount or a proportion, so the mat looks optically centered
   • Photo preview — add a photo (kept on your device, never uploaded) to see it cropped into the opening
   • Per-opening collage photos — fill every opening at once, then fine-tune or replace any single cell
   • Enlarge preview — a “View larger” button opens the current preview, photos and all, in a centered modal

   Decimal readout, tidier measurements

   A new Decimals toggle shows exact decimals instead of ruler fractions, and every calculator now stays internally consistent in the unit you're working in.

   • Decimals toggle — switch any calculator from 1⁄16″ / mm to exact decimals (e.g. 1.938″ / 4.92 cm)
   • Measurements now reconcile in your selected unit; the converted second unit is shown as a labelled reference

   Two new framing guides

   Two in-depth guides join the library, each with original diagrams, a worked example and an FAQ.

   • Glass vs acrylic for picture frames — weight, clarity, UV and cleaning, plus the exact glazing cut size
   • How to frame a cross-stitch — wash, lace over board, mat and glaze a finished stitched piece
