Cable run planner
Measure a route including bends and slack; compare it with a cable length. This does not verify USB speed, power or electrical suitability.
Runs only in this browser. Inputs are not sent to us or saved automatically. Copy any result you want to keep before leaving the page.
Use the same measurement unit for every length (for example, all centimetres or all inches).
Use the result as one part of the decision
The tool uses only the values you enter. Measure the actual space or package, confirm the manufacturer’s instructions and compare the relevant buying guide before shopping. It does not verify product claims, compatibility, safety or suitability for your circumstances.
