Cable Length Calculator
Estimate total cable footage, material boxes, and cost for your next structured cabling project — including risers, service loops, and waste.
Project Estimator
Calculate Your Cable Requirements
Define cable run groups, add vertical risers, and set your slack allowance to get an accurate bill of materials.
Define each group of cable runs with average distance and quantity.
Extra cable for service loops, termination waste, and routing detours.
Planning Tips
Structured Cabling Best Practices
Get accurate estimates and avoid costly re-pulls.
Measure Actual Pathways
Walk the route from the IDF/MDF to each drop location. Account for ceiling plenum routing, wall penetrations, and J-hooks — straight-line distance underestimates by 20-30%.
Budget 10-15% Service Loops
Leave 10 ft of slack at each end for re-termination and future moves. Service loops at ceiling drop points and patch panels save time during adds/moves/changes.
Stay Under 295 ft (90m)
TIA-568 limits permanent link to 90 meters / 295 feet for copper. If your longest run exceeds this, plan for a fiber backbone or additional IDFs.
