15 Foot Ethernet Cable: Desk to Outlet
Quick answer / TL;DR: Short answer: a 15 ft (4.5 m) Cat6 patch cord is the standard desk-to-outlet length. Any category works electrically; choose Cat6 for headroom and a snagless or standard moulded boot for handling. Leave a service loop at the desk end so the device can be moved without unplugging, and secure the excess rather than letting it coil on the floor.
Fifteen feet is the length that reaches from a wall outlet to a desk that has been arranged for people rather than for cabling: around a monitor, behind a drawer, up to a standing-desk frame. It is also long enough that the excess has to be managed.
This is the 15 ft guide: why this length dominates desk patching, the category and boot choice, and the slack management that keeps a workstation tidy.
Why 15 Feet Dominates
| The factor | The effect |
|---|---|
| Outlet position | Rarely where the desk ended up |
| Desk furniture | Drawers and monitor arms consume reach |
| Standing desks | Height travel needs slack |
| Service loop | A metre of spare is normal |
The length is a compromise between the outlet the building provided and the desk the occupant wanted.
Category and Boot
- Gigabit at 4.5 m: any category works
- Cat6 for 2.5G headroom at little extra cost
- Snagless boots where cords get handled
- Two colours to separate data from voice
At this length the electrical differences are negligible; the handling differences are not.
Slack Management
| The practice | The benefit |
|---|---|
| Service loop at the desk | Device can move without unplugging |
| Velcro tie, not a cable tie | No jacket deformation |
| Route along the desk leg | No floor coil to vacuum over |
Standards and Verification
| The reference | The relevance |
|---|---|
| TIA-568.2-D | Cord requirements |
| IEEE 802.3ab | Gigabit over twisted pair |
| Field test | Channel test where the run is permanent |
Per-SKU construction is not provided in the knowledge base. At 4.5 m the channel margin is large in any category.
Real-World Applications
The open-plan desk
Sixty desks in a new layout: 15 ft Cat6 cords with service loops – the fit-out matching the furniture plan rather than the old outlet positions.
The standing desk
A sit-stand frame travelling half a metre: the cord routed with a loop at the frame – no strain at the plug through the travel.
The floor coil
A 15 ft cord left coiled on the floor: vacuumed over, jacket scuffed, one pair intermittent. Replaced and the excess tied to the desk leg – the slack managed.

Frequently Asked Questions
Is 15 ft a standard ethernet length?
It is one of the most common desk-to-outlet lengths, suited to reaching around furniture with slack to spare.
Cat5e or Cat6 at 15 ft?
Both work; Cat6 adds 2.5G headroom for a small price difference.
How much slack should a desk cord have?
About a metre of service loop, tied with velcro so the device can move without unplugging.
Can a 15 ft cord be used for a wall run?
No – use rated cable to an outlet; cords are not for in-wall installation.
