In the world of smartphones, tablets, and modern electronics, the screen to body ratio has become a crucial specification for consumers and manufacturers alike. This metric tells us how much of a device’s front is actually occupied by the screen, compared to the total front surface area. A higher screen-to-body ratio generally means slimmer bezels and a more immersive display experience.
Whether you’re comparing phones, designing a new gadget, or simply curious about your device’s design efficiency, our Screen to Body Ratio Calculator offers a quick and reliable solution. Enter the screen area and body area of your device, and instantly see the screen-to-body ratio expressed as a percentage.
What is Screen to Body Ratio?
The screen-to-body ratio is the proportion of the screen’s surface area to the entire front surface area (the body) of a device. It’s expressed as a percentage and indicates how efficiently the front of the device is used for display purposes.
For example:
- A phone with a 90% screen-to-body ratio means 90% of the front is display, and only 10% is taken up by bezels, buttons, or borders.
- Devices with higher ratios tend to look more modern and offer better viewing experiences.
How to Use the Screen to Body Ratio Calculator
Using our calculator is simple and requires just two inputs:
Steps:
- Enter the total screen area (in mm²): This is the surface area of the display itself.
- Enter the total body area (in mm²): This is the entire front surface of the device, including the screen, bezels, and frame.
- Click the “Calculate” button: The result will be displayed instantly below the form.
The result will show your screen-to-body ratio as a percentage, rounded to two decimal places.
Formula Used
The calculator uses the following basic mathematical formula:
Screen to Body Ratio (%) = (Screen Area / Body Area) × 100
This formula determines what percentage of the body area is occupied by the screen.
Example Calculation
Let’s walk through an example to better understand how the formula works.
Example:
- Screen Area = 85,000 mm²
- Body Area = 100,000 mm²
Calculation:
Screen to Body Ratio = (85,000 / 100,000) × 100
= 0.85 × 100
= 85%
So, the screen occupies 85% of the total front body area.
Why Screen to Body Ratio Matters
- Aesthetic Appeal: Devices with high screen-to-body ratios look sleek and modern.
- User Experience: A larger screen area improves viewing angles and immersive content consumption.
- Space Optimization: Reducing bezels allows manufacturers to fit larger displays into smaller devices.
- Competitive Advantage: Consumers often prefer phones with more screen space without increasing the overall size.
Factors Affecting Screen to Body Ratio
- Bezel Size: Thicker bezels lower the ratio.
- Camera Placement: Pop-up or under-display cameras can increase the ratio by removing front cutouts.
- Buttons and Sensors: Physical buttons and large sensor areas reduce screen coverage.
- Aspect Ratio: A taller screen doesn’t always mean a better screen-to-body ratio—it depends on how it fits the body.

Tips for Accurate Input
- Always use millimeter square (mm²) as the unit for both screen and body areas.
- If you don’t have exact screen area data, use length × width of the visible screen area.
- Ensure both screen and body area measurements are taken from the front face only, not the side or back.
Frequently Asked Questions (FAQs)
1. What is screen to body ratio?
It’s the percentage of the front surface area of a device that is occupied by the screen.
2. Why is it important in mobile phones?
It reflects how immersive and efficient the display design is.
3. Is a higher screen to body ratio better?
Usually, yes. A higher ratio means fewer bezels and more screen area.
4. What unit should I use in the calculator?
Use square millimeters (mm²) for both screen and body area inputs.
5. How do I calculate screen area manually?
Multiply screen width by screen height in millimeters.
6. Does screen curvature affect the ratio?
Yes, curved screens may have slightly more area than flat ones.
7. Are screen to body ratios accurate across manufacturers?
Not always. Some brands round up or calculate differently. This tool gives a neutral, formula-based answer.
8. Can I use inches instead of mm²?
The calculator is based on mm², but you can convert inches to mm first.
9. How to convert inches to mm²?
1 inch = 25.4 mm. Area = length in mm × width in mm.
10. Is this calculator suitable for tablets or laptops?
Yes, it works for any rectangular device where you know the screen and body areas.
11. What happens if the screen area is larger than the body area?
The result will be over 100%, which usually indicates an input error.
12. Does it consider camera notches or punch-holes?
No. It calculates total visible screen area, not viewable content.
13. What is a good screen to body ratio in phones?
Modern phones often exceed 85–90%. Older models may have 60–70%.
14. Does screen-to-body ratio affect battery life?
Indirectly. More screen area can mean higher power consumption.
15. Can this be used for smartwatches?
Yes, as long as you know the areas, even circular shapes can be calculated by converting to mm².
16. What about foldable devices?
You can calculate based on either unfolded or folded screen areas, depending on your purpose.
17. Can I use this for designing a device prototype?
Absolutely. It helps evaluate screen layout efficiency.
18. Is there an app version of this tool?
Currently, it’s available as a web tool only.
19. Do screen protectors affect the ratio?
Not in calculation, unless they add to the visible screen boundary.
20. Is the calculator free to use?
Yes, our Screen to Body Ratio Calculator is 100% free and online.
