How Big Is a 20 Inch Monitor? Exact Dimensions & Guide 2026 | Easy Compare
The 20-inch monitor occupies a transitional position in desktop display history — larger than the 19-inch displays that were once standard in budget offices, but just below the 22-inch size that became the new entry-level norm in the 2010s. Today, 20-inch monitors are rarely sold new, but millions remain in use across homes, offices, and secondary workstation setups. This guide covers exact dimensions, resolution specifications, viewing distances, and a clear comparison to modern alternatives.
20-Inch Monitor: Exact Dimensions
All 20-inch monitors use a 16:9 aspect ratio. Here are the precise screen measurements:
| Measurement | Inches | Centimeters |
|---|---|---|
| Screen width | 17.4" | 44.2 cm |
| Screen height | 9.8" | 24.9 cm |
| Total width (with bezels) | 18.5–19.5" | 47.0–49.5 cm |
| Total height (with stand) | 14–17" | 35.6–43.2 cm |
| Screen area | 171 sq in (1,103 cm²) | — |
| Weight (without stand) | 5–8 lbs | 2.3–3.6 kg |
At just over 17 inches wide, the 20-inch monitor has a reasonably compact footprint. It fits comfortably on a standard 48-inch desk alongside a keyboard and peripherals. Stand bases typically extend 6–8 inches in depth, so total desk depth consumption (stand + monitor) is around 8–10 inches.
Resolution Options for a 20 Inch Monitor
| Resolution | Name | PPI | Sharpness | Availability |
|---|---|---|---|---|
| 1920×1080 | FHD / 1080p | 110 PPI | Sharp | New models, some refurb |
| 1600×900 | HD+ | 92 PPI | Adequate | Common in older refurb units |
| 1366×768 | HD | 78 PPI | Soft | Budget/older units only |
The 110 PPI of a 1080p 20-inch monitor is a comfortable density for desktop use at 2 feet — sharper than a 24-inch 1080p (92 PPI) but physically much smaller. The 1600×900 resolution found in many older 20-inch models is serviceable but noticeably less crisp, particularly for text-heavy work. Avoid 1366×768 at 20 inches if possible; the low PPI makes text look rough at close viewing distances.
Ideal Viewing Distance for a 20 Inch Monitor
| Resolution | PPI | Minimum Distance | Comfortable Distance |
|---|---|---|---|
| 1920×1080 | 110 PPI | 1.3 ft (40 cm) | 2.0–2.5 ft (60–76 cm) |
| 1600×900 | 92 PPI | 1.5 ft (45 cm) | 2.0–3.0 ft (60–91 cm) |
20 vs 22 vs 24 vs 27 Inch Monitor Comparison
| Size | Width | Height | Screen Area | PPI (1080p) |
|---|---|---|---|---|
| 20" | 17.4" | 9.8" | 171 sq in | 110 PPI |
| 22" | 19.2" | 10.8" | 207 sq in | 100 PPI |
| 24" | 20.9" | 11.8" | 247 sq in | 92 PPI |
| 27" | 23.5" | 13.2" | 310 sq in | 82 PPI |
Upgrading from 20 inches to 22 inches adds 21% more screen area. Jumping directly to 24 inches adds 44% more area — a much more worthwhile investment for the similar price difference.

Best Uses for a 20 Inch Monitor in 2026
- Secondary or tertiary displays: A 20-inch monitor works well as a secondary screen for reference material, chat, dashboards, or media playback alongside a larger primary display.
- Small office or cubicle workstations: Where desk space is limited and tasks are simple — email, basic data entry, forms — a 20-inch manages adequately.
- Home server dashboards: For a Raspberry Pi, NAS, or home server status monitor, a 20-inch provides useful visibility without taking up much space.
- Kids' computer setups: For a child's desk doing homework, basic browsing, and educational software, a 20-inch is fine and age-appropriate in scale.
- Light gaming on budget setups: At 1080p and 110 PPI, a 20-inch delivers acceptable image quality for casual gaming, though the small screen limits immersion.
Upgrading From a 20 Inch Monitor
If you're using a 20-inch as your primary monitor for daily computing, upgrading to 24 inches is the recommended step. The visual improvement is substantial, the price of entry-level 24-inch IPS panels has dropped to $100–$130, and you gain modern connectivity (HDMI, DisplayPort) that many older 20-inch monitors lack.
For those wanting maximum value: a 27-inch 1440p monitor (around $180–$250) delivers 81% more screen area than a 20-inch and a significant resolution jump — a transformative upgrade that will serve you well for 5+ years.
Frequently Asked Questions
How wide is a 20 inch monitor?
A 20-inch 16:9 monitor measures approximately 17.4 inches (44.2 cm) wide and 9.8 inches (24.9 cm) tall. With bezels included, total physical width is typically 18.5–19.5 inches.
What is the best resolution for a 20 inch monitor?

Can I still buy a new 20 inch monitor?
New 20-inch monitors are rare in 2026 — most manufacturers have shifted their entry-level lineup to 21.5–22 inches. Budget 20-inch monitors can be found on the used market for $20–$60. If buying new, a 22-inch or 24-inch monitor is the practical alternative at nearly the same or slightly higher price.
Is a 20 inch monitor good for office work?
A 20-inch monitor handles basic office tasks — email, word processing, spreadsheets, and web browsing — without serious difficulty. It becomes limiting when multitasking, running multiple windows, or doing design work. For a primary office display in 2026, most users would benefit from upgrading to 22–24 inches.
