L-shaped desks solve the space problem and create a cable problem. With two work surfaces meeting at a corner, devices end up spread along nearly three metres of desktop: monitors on one wing, a laptop or printer on the other, and the power socket stubbornly behind the far end. The corner itself is a dark triangle that swallows cables and is almost impossible to reach once the desk is against the wall. Planning around that corner is the whole game.
📄 In This Review
Quick answer: Our top pick in 2026 is the Far end of main wing — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
Decide where the power lives
On a straight desk, the power strip goes wherever the wall socket is. On an L-shaped desk, it should go at the corner, because the corner is the geometric centre of both wings. Cables from the main wing and the return wing each travel roughly half the distance they would if the strip sat at one end. If the wall socket is far from the corner, run one heavy-duty extension or the strip’s own long cord along the wall to the corner rather than running many device cables the other way.
| Power strip location | Longest device run | Verdict |
|---|---|---|
| Far end of main wing | Up to 2.5–3 m to the return wing | Messy, needs long cables |
| Far end of return wing | Similar, plus monitors furthest away | Worst for monitor-heavy setups |
| Under the corner | About 1.2–1.6 m to either end | Best balance for most layouts |
| Two strips, one per wing | Under 1 m | Tidiest, needs two wall runs or a linked strip |
Use two trays, not one long one

A single straight tray cannot follow the corner. Mount one tray under each wing, with their inner ends meeting near the corner, and place the power strip where they meet. Cables from each wing drop into their own tray and travel inward. Mesh baskets are useful here because cables can pass through their sides where the two trays meet at 90 degrees.
Watch the corner support
Many L-shaped desks have a leg, panel or metal bracket under the corner. Measure its footprint before buying trays so they do not collide with it. On electric L-shaped standing desks, there may be a third motorized leg at the corner and a crossbar along each wing, leaving less mounting room than you expect.
Solving the dead corner
The triangle behind the corner is the worst place for anything you need to access. Use it for things you never touch: the power strip’s surge-protector plug, the router’s power brick, the desk motor’s control box. Put anything you need to unplug occasionally, such as a laptop charger or phone cable, on the front half of the desk where you can reach it.
A corner grommet or pass-through
If the desk has a grommet near the corner, it is the natural drop point for cables from monitors on both wings. If it does not, a clamp-on pass-through tray at the rear corner avoids drilling and gives cables somewhere to go besides draping over the back edge.
Common L-shaped layouts and how to cable them
Monitors in the corner
Placing monitors diagonally in the corner gives the deepest viewing distance and is popular for large or ultrawide screens. Cables drop straight down behind the monitor stand into the corner tray junction, which is convenient. The downside is that the corner is hard to reach when you need to swap a cable, so leave generous slack and label everything.
Monitors on the main wing, paper on the return
This is the most common office layout. Treat the main wing like a normal straight desk with its own tray and drop, and keep the return wing mostly cable-free except for a lamp and a charger. Only a printer or scanner should need power on the return side.
Two computers, one per wing
Work laptop on one side, personal PC on the other: give each wing its own strip and tray so the two setups never tangle. A KVM switch or a monitor with two inputs can let both machines share displays, but put the switch on the main wing where the monitors are.
Floor cables and chair paths
An L-shaped desk means your chair rolls in an arc between the wings. Any cable on the floor inside that arc will be run over. Route everything along the underside of the desk and down at the rear corner, never across the floor in front of either wing.
FAQ
How long should my cables be for an L-shaped desk?
With the power strip at the corner, most device cables need 1.5–2 m. Monitor video cables running from a tower at one end to a screen at the other may need 3 m; check the rated length for high-refresh DisplayPort connections.
Is a cable spine useful on an L-shaped standing desk?
Yes. Place it near the corner where the power strip lead drops to the floor, and make sure it clears the third leg during travel.
Bottom line
Put the power at the corner, use a tray under each wing that meets there, reserve the hard-to-reach corner for things you never touch and keep the chair’s arc free of cables. An L-shaped desk then feels like two tidy desks rather than one sprawling tangle.
