A 24-inch and a 27-inch monitor side by side - desk fit guide
A 24-inch plus a 27-inch monitor fit a 55-inch desk flat with about 5 inches per side, but the mismatched heights and PPI mean the 27-inch carries primary work and an arm aligns the tops.
Pairing a 24-inch with a 27-inch monitor is common when you upgrade one screen at a time. The panels span about 44.4 inches (113 cm) flat, which fits a 55-inch (140 cm) desk with roughly 5 inches (13 cm) of clearance per side. The layout works, but the mismatched panel heights and pixel densities take a little tuning to look right.

How this is calculated
The 24-inch panel is about 20.9 inches (53 cm) wide and the 27-inch is about 23.5 inches (60 cm) wide, for a flat span of roughly 44 inches (113 cm). Height is the mismatch: a 24-inch 16:9 panel is about 11.8 inches (30 cm) tall while the 27-inch is about 13.2 inches (34 cm), so the tops will not align at the same base height without an arm. If one panel is 1080p and the other 1440p, the pixel density gap (about 92 PPI versus 109 PPI) is visible when you move text between them. Keep the sharper 27-inch for primary work.
Verdict
The 24-inch panel at about 20.9 inches (53 cm) wide plus the 27-inch at about 23.5 inches (60 cm) spans roughly 44 inches (113 cm) against a 55-inch (140 cm) desk, leaving approximately 5 inches (13 cm) of clearance per side, an easy fit. The layout quirks are height and density. A 24-inch panel is about 11.8 inches (30 cm) tall against the 27-inch at about 13.2 inches (34 cm), so the tops misalign without an arm, and a 1080p-versus-1440p pair leaves a visible 92 to 109 PPI gap when text moves between them. The working pattern is to run the sharper 27-inch as primary and the 24-inch for chat and monitoring, with an arm aligning the panel tops for a cleaner look.
