Convert TV and monitor screen sizes between inches and centimeters. Screen sizes are measured diagonally.
centimeters = inches Γ 2.54
1 inch = 2.54 cm
TV and monitor sizes are measured by the diagonal length of the screen, from one corner to the opposite corner. This standard is used worldwide for televisions, monitors, laptops, and tablets.
Example: 55β³ Γ 2.54 = 139.7 cm
| Screen Size (in) | Diagonal (cm) |
|---|---|
| 24β³ | 60.96 cm |
| 27β³ | 68.58 cm |
| 32β³ | 81.28 cm |
| 43β³ | 109.22 cm |
| 50β³ | 127 cm |
| 55β³ | 139.7 cm |
| 65β³ | 165.1 cm |
| 75β³ | 190.5 cm |
32β³ TV = 81.28 cm
55β³ TV = 139.7 cm
27β³ Monitor = 68.58 cm
Screen size and screen resolution are closely related, but they measure different things. While TV size refers to the physical diagonal measurement, resolution defines how many pixels are displayed on the screen. Understanding this difference helps you choose the right TV or monitor for your space, usage, and viewing distance.
1080p, also known as Full HD, has a resolution of 1920 Γ 1080 pixels. It is commonly used in smaller TVs, budget monitors, laptops, and older televisions.
4K, also called Ultra HD (UHD), has a resolution of 3840 Γ 2160 pixels. It offers four times the detail of 1080p and is the current standard for modern TVs and monitors.
8K displays have a resolution of 7680 Γ 4320 pixels, delivering extremely high pixel density. While still emerging, 8K TVs are designed for very large screens and future content.
Choosing the right resolution depends on your screen size and viewing distance. Larger screens benefit from higher resolutions, while smaller screens may not show noticeable improvements beyond 1080p.
Using a TV and monitor size converter helps you compare physical dimensions alongside resolution, ensuring the screen fits your room and delivers the image quality you expect.
Choosing the correct TV or monitor size depends heavily on your viewing distance. Sitting too close can make pixels visible, while sitting too far reduces image detail and immersion. This table helps you match screen size with the ideal viewing distance for the best experience.

For higher resolutions like 4K and 8K, you can sit closer without seeing individual pixels, making large screens more immersive. Always consider both screen size and room layout when choosing a TV or monitor.
Field of View (FOV) describes how much of your visual field is filled by the TV or monitor screen. A larger FOV creates a more immersive experience, while a smaller FOV feels more distant. Industry standards like THX and SMPTE provide recommended FOV angles to help determine the ideal viewing distance and screen size.
The Society of Motion Picture and Television Engineers (SMPTE) recommends a minimum viewing angle of 30Β°. This ensures that the screen is large enough to feel engaging without overwhelming the viewer.
THX recommends a larger 36Β° to 40Β° field of view for a more immersive, theater-style experience. This places the viewer closer to the screen, increasing detail and engagement β especially noticeable on high-resolution displays.
Higher screen resolutions allow you to sit closer without noticing individual pixels. This means 4K and 8K TVs can safely use a wider FOV, following THX recommendations without image quality loss.
When choosing a TV or monitor, balancing screen size, viewing distance, and resolution using THX or SMPTE standards ensures an optimal and comfortable viewing experience.
No. TV size refers only to the visible screen area, not the bezel.
Yes. Monitors, TVs, laptops, and tablets all use diagonal measurement.
This comes from historical US manufacturing standards that became global.
