Calculateur de Position de Crochet & Clou pour Accrochage de Cadre
Trouvez la hauteur de fixation murale exacte et les coordonnées horizontales à partir de la taille du cadre, de la hauteur de centre et de la chute réelle de la quincaillerie.
Measure with wire pulled taut on the hook
How it works
How to use it: choose the final frame centre height, then measure from the frame's top edge down to the fixing point while the wire or hardware is carrying its load. For two hooks, also enter their centre-to-centre spacing.
Formula. Frame top = centre height + half the frame height. Fixing height = frame top - loaded hardware drop. A centered frame starts at (wall width - frame width) / 2; two hooks sit half their spacing either side of the wall centre.
Worked example. An 800 mm-high frame centered at 1450 mm has its top at 1850 mm. With a loaded hook drop of 100 mm, mark the wall at 1750 mm from the floor.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Wall width
- 3000 mm
- Frame width
- 600 mm
- Frame height
- 800 mm
- Desired frame centre height
- 1450 mm
- Frame top to loaded fixing point
- 100 mm
- Fixing points
- One centered hook
- Distance between two hooks
- 300 mm
Primary result: Fixing height: 1750.0 mm.
Before using the result
- Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
- Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
- When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.
Limitations
Measure the actual loaded wire sag and the hook's real support point. Frames, wires and wall fixings can move under load. Confirm wall structure, fixing capacity and hidden services before drilling; this calculator does not select safe hardware.
Frequently asked questions
Why measure the wire while pulled tight?
Loose wire sits higher than it will on the wall. Pulling it toward the intended hook gives a more realistic loaded drop.
Is this the same as the Gallery Wall Planner?
No. This finds fixing coordinates for one chosen frame position. Use Gallery Wall Planner to compose and space several frames.
