Size difference
The 27″ 1440p has 29% more screen area than the 24″ 1440p, and is 2.8″ wider and 1.6″ taller. The 24″ 1440p measures 20.7″ × 11.7″ (53 × 30 cm) with a 16:9 aspect ratio. The 27″ 1440p measures 23.5″ × 13.2″ (60 × 34 cm) at 16:9. Panel sizes exclude bezels and stands, so allow about 1–3 cm extra on each side.
Sharpness and pixel density
The 24″ 1440p is sharper at 123 PPI versus 109 PPI on the 27″ 1440p, a 13% increase in pixel density. Individual pixels stop being visible to 20/20 vision beyond about 28″ (71 cm) on the 24″ 1440p and 32″ (80 cm) on the 27″ 1440p.
Workspace
Both show nearly the same number of pixels (3.7 vs 3.7 MP), so at 100% scaling they fit the same amount of content.
On a Mac
The 24″ 1440p: sharp, not Retina. It runs at native 2560 × 1440, with a comfortable UI size and clean pixel mapping. Text is sharp, but you may notice individual pixels up close. The 27″ 1440p: sharp, not Retina. It runs at native 2560 × 1440, with a comfortable UI size and clean pixel mapping. Text is sharp, but you may notice individual pixels up close.
Why this matters: macOS draws its interface at exactly 1× or 2×, so displays near 110 or 220 PPI look best. Read the Mac monitor guide or how we rate sharpness.
Desk and viewing distance
For comfortable viewing, sit roughly 30″ (76 cm) from the 24″ 1440p and 34″ (86 cm) from the 27″ 1440p. A desk at least 74 cm deep keeps the larger screen from feeling too close.
