MarkSpan: Baluster Spacing
Even Marks Measured from Edge
$2.99 · Designed for iPad. Not verified for macOS.
Enter length and count, get every mark position from the edge. No stacking error, no adding up gaps. Circle divide, diagonal check, and slope length included. No ads.
Enter a length and a count. MarkSpan gives you every mark position measured from the edge — so you can hook your tape once and mark them all, with no stacking error.
Most spacing calculators only give you the gap size, leaving you to add it up mark by mark. MarkSpan gives you the running dimensions: 300.0, 600.0, 900.0 — exactly what you mark with a tape.
LAYOUT MODES
- Even gaps (ends included) — shelf pins, fence boards
- Marks at both ends — fence posts, railing balusters
- Even centers — screws, handles, joists
- Fixed pitch — studs and joists at 455 mm / 16 in, with the leftover shown
SITE TOOLS
- Circle divide: chord length you can step off with a compass — not just angles
- Diagonal check: target diagonal for a square frame, and which corner to push
- Slope length: true length along a slope from angle, rise/run, sun-gradient or pitch
BUILT FOR THE JOB SITE
