What angle should dual monitors be at?

For equal-use setups, 15-20 degrees inward per screen is ideal. For primary and secondary setups, 30-45 degrees for the secondary screen is common.

Should dual monitors be the same size?

Ideally yes - same size and resolution makes alignment simpler. A larger primary and smaller secondary is also a practical and common setup.

Do I need a special stand for dual monitors?

Not strictly. A dual monitor arm offers full independent height, angle, and tilt adjustment for both screens and frees up significant desk space.

Setup Guide

How to set up dual monitors ergonomically

The goal is to make both screens accessible with eye movement or minimal head rotation for your primary workflow. Frequent full head-turns defeat the purpose and cause neck fatigue.

Equal Use Setup

If you use both screens roughly equally - typical for developers, traders, or video editors - position both monitors symmetrically at 15-20 degrees inward each. Your head should be centred between the two screens. Bezels should meet or nearly meet at the centre point directly in front of you.

Primary Plus Secondary Setup

If you have one main screen and one secondary for references or messaging, place the primary directly in front of you and the secondary to the side at 30-45 degrees. A slight head rotation should be enough to see it - not a full turn.

Monitor Size (x2)	Min Desk Width	Ideal Desk Width	Recommended Angle
2 x 24"	130 cm	150 cm	15-20 deg each
2 x 27"	140 cm	160 cm	15-20 deg each
2 x 32"	160 cm	180 cm	20-25 deg each
27" + 24" mixed	135 cm	155 cm	Primary 0, secondary 30 deg

💡

Bezel gap: Position monitors as close together as physically possible - 0-5mm gap. Some users offset one screen slightly further back to minimise the visual distraction of the seam in the centre of the workspace.

Also check individual monitor distance

Each screen in your dual setup should still be at the correct viewing distance.

Common Questions

Frequently asked questions

For equal-use setups, 15-20 degrees inward per screen is ideal. This keeps both screens within a comfortable field of view without requiring full head turns. For primary/secondary setups, 30-45 degrees for the secondary screen is common.

Ideally yes - same size and resolution makes alignment simpler and eliminates scaling differences. A larger primary and smaller secondary is practical and common. Avoid mixing very different resolutions as this causes visual inconsistency in multi-window workflows.

Not strictly - you can use two individual stands, though desk space becomes tight. A dual monitor arm gives full independent adjustment for both screens and frees up significant desk space. Freestanding dual stands are a cheaper alternative if clamping is not practical.

Yes - this is one of the most common dual-screen setups. Position the external monitor directly in front at correct ergonomic height, and use the laptop screen as a secondary display to the side or lower. A laptop stand and external keyboard and mouse makes this much more comfortable for extended use.
