P3 vs P4 vs P5 vs P6 SMD Screen: Which Pixel Pitch Is Right for Your Project?
Understand the difference between P3, P4, P5 and P6 SMD LED screens, including viewing distance, image clarity, screen size, indoor and outdoor applications, and project cost.
P3, P4, P5 or P6 — Which One Should You Choose?
The right pixel pitch depends mainly on viewing distance, screen size, installation environment and content type. A smaller pixel pitch generally provides higher pixel density and better close-viewing detail, while a larger pitch can be practical for larger screens viewed from farther away.
For many outdoor advertising applications, P4 and P5 can provide a practical balance between image quality, viewing distance and project cost. P6 can make sense for larger displays where the audience is farther away. P3 is useful when higher detail is required at a relatively closer viewing distance.

Use the sections below to compare pixel pitch before requesting a quotation.
What Is Pixel Pitch in an SMD LED Screen?
Pixel pitch is the distance between the centres of adjacent LED pixels on an LED display. It is normally measured in millimetres and written as P2.5, P3, P4, P5, P6 and so on.
The number is important because it affects pixel density, image detail and the distance from which viewers can comfortably see the display.
In simple terms, a smaller number means the pixels are packed closer together. This generally makes the display more suitable for close viewing, while larger pitches are commonly used for bigger screens and longer viewing distances.

P3 means approximately 3 mm pixel spacing, while P6 means approximately 6 mm pixel spacing.
P3 vs P4 vs P5 vs P6 SMD Screen Comparison
The table below provides a practical starting point. Final selection should be based on actual viewing distance, screen dimensions, environment and content requirements.
| Pixel Pitch | Typical Use | Viewing Distance* | Detail Level | Common Environment |
|---|---|---|---|---|
| P3 | Closer outdoor / premium displays | Approx. 4–12 m | Higher | Outdoor / Semi-outdoor |
| P4 | Outdoor advertising | Approx. 6–20 m | High | Outdoor |
| P5 | Large advertising displays | Approx. 7–25 m | Good | Outdoor |
| P6 | Large-format outdoor screens | Approx. 9–30 m | Good at distance | Outdoor |
*Viewing-distance ranges are planning references rather than universal technical limits. Actual suitability depends on screen size, content, viewing conditions and the selected LED module.
P3 SMD Screen
P3 provides a relatively fine pixel pitch for an outdoor LED display. It can be considered when viewers are closer to the screen or when the project requires more visual detail than a larger pitch can provide.
P3 can be suitable for:
- Closer-view outdoor advertising
- Commercial building displays
- Premium outdoor installations
- Applications where image detail matters
P4 SMD Screen
P4 is a common outdoor pixel-pitch option for projects that need a balance between image quality and viewing distance. It can work well for commercial advertising screens, façades and other high-visibility outdoor applications.
P4 can be suitable for:
- Outdoor advertising screens
- Commercial buildings
- Roadside displays
- Medium-distance viewing
P5 SMD Screen
P5 is widely considered for larger outdoor advertising displays where the audience is generally farther from the screen. Its larger pixel spacing can be practical when the screen is viewed from a greater distance.
P5 can be suitable for:
- Outdoor advertising
- Large commercial displays
- Building façades
- Roadside and high-visibility locations
P6 SMD Screen
P6 is a larger-pitch option that can be practical for large outdoor screens viewed from farther away. It can be considered for advertising installations where screen scale and visibility are more important than very close-range pixel detail.
P6 can be suitable for:
- Large outdoor advertising screens
- Longer viewing distances
- Large-format commercial displays
- Selected billboard applications
How Viewing Distance Affects Pixel Pitch
Viewing distance is one of the most important factors when selecting an SMD LED screen. The same pixel pitch can look different depending on how close the audience is to the display.
Close Viewing
Individual pixels are easier to distinguish, so a finer pitch can be more appropriate.
Comfortable Viewing
At an appropriate distance, the pixels visually blend together and the display appears smoother.
Long Distance
Larger pitches can become practical when the audience is far from a large-format display.

Does a Smaller Pixel Pitch Cost More?
Generally, finer-pitch LED displays require more pixels per square metre. This can increase the cost of the LED modules and related hardware.
However, pixel pitch is only one part of the total project cost. Screen dimensions, cabinet type, controller, power distribution, steel structure, installation, transportation, calibration and site conditions can also affect the final quotation.
This is why comparing two quotations only by price per square foot can be misleading if their technical specifications and project scope are different.

P3, P4, P5 and P6: Indoor or Outdoor?
Pixel pitch alone does not determine whether an LED screen is suitable. The installation environment also determines brightness, cabinet protection, weather resistance and other technical requirements.
Indoor SMD Screens
Indoor displays are designed for controlled environments such as offices, conference rooms, showrooms, malls, events and reception areas.
Explore Indoor SMD Screens →Outdoor SMD Screens
Outdoor displays need to handle daylight, weather and longer viewing distances. Cabinet protection, brightness and installation structure are important considerations.

Define the Environment
Decide whether the display will be installed indoors, outdoors or in a semi-outdoor location.
Measure Viewing Distance
Identify the closest regular viewing position rather than estimating distance from the installation point.
Determine Screen Size
Measure the available width and height and calculate the required display area.
Consider Your Content
Video, graphics, text and detailed content can have different visual requirements.
Compare Complete Quotes
Compare modules, cabinets, controller, structure, installation, calibration, warranty and support — not only the price.

P3, P4, P5 & P6 SMD Screen FAQs
Is P3 better than P5? +
P3 and P5 serve different viewing requirements. P3 has a smaller pixel pitch and can provide better close-range detail, while P5 can be practical for larger displays viewed from farther away. The appropriate choice depends on the project.
What is P4 SMD screen used for? +
P4 can be considered for outdoor advertising, commercial displays, façades and other applications where a balance between image detail and viewing distance is required.
Is P5 suitable for outdoor advertising? +
P5 can be a practical option for many outdoor advertising applications, particularly where viewers are at a moderate or longer distance from a large-format display.
When should I consider P6? +
P6 can be considered for larger outdoor screens viewed from farther away. It is important to evaluate the actual viewing distance and screen dimensions before selecting it.
Does smaller pixel pitch always mean better? +
Not necessarily. A smaller pixel pitch provides higher pixel density, but it can also increase project cost. If the audience is far from a large screen, a larger pitch may provide an appropriate visual result without paying for unnecessary close-view detail.
How can I calculate the right SMD screen for my project? +
Start with screen dimensions, viewing distance, installation environment and content type. You can use the LUMAX SMD Screen Calculator for an initial recommendation.
