Triple monitor setup planner

Three screens give you the most room to work or the widest field of view for sim racing, but they need a lot of desk. Lay them out to scale and see what fits.

How wide is a triple monitor setup?

Flat in a row, three 24-inch monitors span about 67 inches and three 27-inch monitors about 74 inches — wider than most desks. Angling the two side screens inward by about 30° brings that down to roughly 59 and 66 inches and puts every screen at a similar distance from your eyes.

Plan on a desk at least 60 inches wide for triple 24s, and about 70 inches for triple 27s.

Triple monitors vs a super ultrawide

A 49-inch 32:9 super ultrawide is about 48 inches wide and 13.3 inches tall, with no bezels. Three 24-inch monitors give about 18% more screen area (roughly 738 vs 626 square inches) but have two bezels across your view; three 27-inch monitors give about 50% more area.

For sim racing and flight sims, triples angled around you give the widest field of view. For office work, a super ultrawide is simpler to set up and has one cable.

Mounting three monitors

A triple arm on one pole needs long reach: the outer screens sit about 22 inches from the pole for 24-inch monitors. Many people use one dual arm plus a single arm, or a wide freestanding bar. Drag the outer screens in the planner to see whether your arm reaches.

Another popular layout is one ultrawide in the middle with two smaller screens turned vertical on either side.

Questions

Triple monitor setup, answered

What is the best size for a triple monitor setup?

Three 24-inch 1080p or 1440p monitors are the most practical: affordable, and they fit on a 60-inch desk when the sides are angled in. Triple 27s need around 70 inches of desk and a strong GPU for gaming.

Is a triple monitor setup worth it for productivity?

If you routinely work across three apps at once — code, docs and a browser, or trading platforms — yes. Otherwise a dual setup or an ultrawide is easier to live with.
