Two 27-inch landscape monitors span about 119.5 cm (47.1 inches)47.1 inches (119.5 cm) flat, and a portrait 27-inch sidecar adds about 34 cm (13 inches)13 inches (34 cm) of width, for a total of roughly 153 cm (60 inches)60 inches (153 cm). That fits a 160 cm (63-inch)63-inch (160 cm) desk with about 3.4 cm (1.3 inches)1.3 inches (3.4 cm) of side room. Angle the panels inward using the configured 15-degree landscape angles and 20-degree portrait angle, and the footprint is about 149.1 cm (58.7 inches)58.7 inches (149.1 cm), leaving roughly 5.5 cm (2.1 inches)2.1 inches (5.5 cm) per side.

How this is calculated

This layout suits developers. The two landscape 27-inch panels handle the main workspace and code editor, while the portrait 27-inch sidecar carries chat, terminals, or long documents. The portrait 27-inch stands about 59.8 cm (23.5 inches)23.5 inches (59.8 cm) tall, at the same base level as the landscape panels. The 1440p portrait 27-inch gives 2560 lines of vertical resolution, enough for roughly 100-120 lines of code at a standard font size.

Verdict

A 160 cm (63-inch)63-inch (160 cm) desk is the natural floor for dual 27-inch landscape panels plus a portrait sidecar, and a VESA 100x100 triple arm is the practical move because three native stands on one surface eat a lot of desk space and add cable clutter. The 119.5 cm (47.1-inch)47.1-inch (119.5 cm) dual landscape footprint plus the 34 cm (13-inch)13-inch (34 cm) portrait sidecar comes to about 153 cm (60 inches)60 inches (153 cm), leaving about 3.4 cm (1.3 inches)1.3 inches (3.4 cm) of clearance per side before angling.

Tilting the panels inward using the configured 15-degree landscape angles and 20-degree portrait angle produces a footprint of about 149.1 cm (58.7 inches)58.7 inches (149.1 cm), leaving roughly 5.5 cm (2.1 inches)2.1 inches (5.5 cm) per side. The 80 cm (31.5-inch)31.5-inch (80 cm) depth does most of the comfort work: the three native stands consume roughly 24 inches (61 cm) of depth in total but the keyboard surface still gets about 22 inches (56 cm), and the resulting 27-28 inch (69-71 cm) viewing distance lands where 1440p 27-inch panels are sharp.

A 80 cm (31.5-inch)31.5-inch (80 cm) depth is comfortable. The three native stands consume about 24 inches (61 cm) of depth in total but leave about 22 inches (56 cm) of keyboard surface and a 27-28 inch (69-71 cm) viewing distance that suits 1440p.
Do I need a triple monitor arm for dual 27 plus vertical 27?
Strongly recommended. A VESA 100x100 triple arm reclaims the three native stands' depth and tames the cable clutter, which is the real payoff on a three-panel layout on one desk.
