Measure the real illuminated path

LED-Strip Length Calculator

Add route segments, gaps, corners, cut intervals, allowance, and roll size to estimate strip length and roll count.

Planning result

11.6 ft planned · 1 roll at 16.4 ft

The illuminated route is 11 ft after gaps, with 5% routing allowance.

Measured segments: 11 ft
Planned gaps: 0 ft
Corners: 4; verify bend or connector method
Roll remainder: 4.8 ft before cut constraints

Verify before acting

Round only after checking marked cut intervals and whether cut sections remain reusable.
Verify controller length, voltage, power supply, connector, and voltage-loss limits.

01

Enter the room, route, or product claim

Inputs remain visible so you can challenge the assumptions.

02

Use the range as a shortlist

The result narrows questions; it does not certify a product or room.

03

Measure and verify

Check the real space, documentation, safety limits, and seller before purchase or installation.
