JYVISIONS LED Planning Tool
LED Pixel Pitch / Viewing Distance Calculator
Compare multiple industry viewing-distance references, then test them against the closest important viewer, primary audience position, screen scale, content and native-resolution needs. The result is a project assessment—not a universal “best pitch” formula.
Enter Your Project Parameters
Use the fields you know. In viewing-distance mode, both the closest important viewer and the primary audience position are required so one rare close position does not automatically control the whole decision.
Project-Based Pitch Assessment
The tool does not average vendor formulas. It keeps each published reference visible, then applies only objective project constraints such as closest-view distance and native pixel count.
Application and content determine which part of the assessment deserves the most attention; they do not apply a hidden multiplier to the math.
Closest-Viewer Constraint
A close-view reference will appear here.
Cross-Industry Reference Methods
Different sources define “comfortable,” “optimal,” “visual acuity,” or “minimum” differently. The table keeps those meanings separate.
| Reference | Pitch at Primary Distance | Horizontal Pixels* |
|---|---|---|
| Run the assessment to populate the reference methods. | ||
*Horizontal pixels appear when screen width is supplied.
Screen Scale & Native Resolution
Add screen width to calculate native horizontal pixels and viewing geometry. Add a target pixel count to test whether it creates a stricter pitch requirement.
Engineering Interpretation
Use the result as a transparent starting assessment. Final selection still requires product availability, budget, screen height/aspect ratio, site conditions and actual viewing geometry.
Why This Tool Does Not Use One Universal Formula
Major LED and professional-AV sources publish different distance relationships because they are not always describing the same viewing condition. Samsung uses a comfortable-viewing rule of about 8 feet per millimeter of pitch. Barco uses an Optimal Viewing Distance rule of about 2 meters per millimeter. Christie publishes both a rough 1 meter-per-millimeter minimum-viewing reference and a separate 3 meters-per-millimeter optimal-viewing table. Planar distinguishes Average Comfortable Viewing Distance from Visual Acuity Distance. AVIXA goes further by separating Basic Decision Making from Analytical Decision Making and considering image size, resolution, viewer position and content detail.
ST01 therefore treats viewing-distance formulas as reference methods, not as competing universal standards. The project assessment keeps the methods visible and adds project-specific constraints without inventing hidden weighting factors.
How to Read the Assessment
- 1
Closest-view constraint: checks whether a rare but important close position creates a coarser-pitch ceiling.
- 2
Primary-audience references: compares the average viewing distance against the published Samsung, Christie, Barco and Planar methods.
- 3
Screen scale: converts screen width and each candidate pitch into approximate horizontal pixel count and viewing angle.
- 4
Native-resolution target: if supplied, calculates the maximum pitch that can still create the requested horizontal pixel count. Use the LED screen size, resolution and aspect ratio guide to verify the full physical canvas.
- 5
Application/content pressure: tells you whether to investigate the finer end, stay balanced, accept a coarser end, or trigger a special engineering review. It does not secretly multiply the pitch result.
Reference Methods Used in ST01
Samsung
Comfort-oriented rule: about 8 ft of viewing distance per 1 mm of pitch (≈2.44 m/mm). Samsung also notes that average viewing distance and cost should be considered rather than automatically buying the finest pitch.
Official Samsung referenceChristie
Christie publishes a general minimum-viewing guideline of about 1 m per 1 mm of pixel pitch, and a separate suggested optimal-viewing table using about 3 m per 1 mm. Christie also emphasizes viewing distance, content type and room size when selecting pixel pitch.

Barco
TruePix uses OVD ≈ 2 × pitch (meters per millimeter) as a rule of thumb and explicitly warns that control-room / small-letter applications may require different evaluation.

Planar separates Average Comfortable Viewing Distance (about 1.72 m/mm at P1.0) from Visual Acuity Distance (about 3.44 m/mm at P1.0).

AVIXA V202.01:2026 determines display image size and relative viewing positions according to Basic vs Analytical Decision Making. ST01 uses that principle as a guardrail: detailed analytical content cannot be reduced to a pitch-distance shortcut.

When the Distance-Only Result May Need to Change
Control Rooms and High-Information Displays
Small text, maps, dashboards, monitoring windows and analytical content can justify focusing on the finer end. AVIXA’s Analytical Decision Making framework is a reminder that line-level detail and display resolution matter, not only pitch-to-distance ratios.
Very Large LED Displays
A rare close position may not represent how the main audience experiences the complete image. Primary viewing distance, screen width, field of view and native canvas can matter more than a single minimum-distance rule.
Fixed 4K / 8K / Custom Canvas
When the client requests a native horizontal pixel count, physical screen width creates an objective pitch ceiling. For example, an 8 m wide display targeting about 3840 horizontal pixels needs roughly P2.08 or finer before module/cabinet rounding.
Transparent LED
Transparent LED adds transparency, asymmetric pitch, brightness, glass conditions and product architecture. ST01 can provide the universal reference layer, but final selection requires a transparent-specific engineering review.
Use the transparent LED display guide for that second layer.
Frequently Asked Questions
Why does ST01 show several reference methods instead of one answer?
Because major manufacturers use different definitions and ratios for minimum, optimal, comfortable and visual-acuity viewing. Showing the methods separately is more transparent than averaging them into a number that none of the sources actually publishes.
What does the Practical Evaluation Band mean?
It is the cross-industry primary-audience envelope, tightened only when the closest important viewer or a native-resolution target creates an objective coarser-pitch ceiling. It is still a planning band, not a final product specification.
Why is average / primary viewing distance required?
The closest viewer may represent only a small part of the audience. For many large-format displays, the primary audience position better reflects how the screen is normally experienced and whether extra pixel density creates visible value.
How does screen width affect the result?
Screen width lets the tool calculate approximate horizontal pixel count for each pitch reference and the screen’s horizontal field of view. It also makes a fixed native-resolution target mathematically testable.
Does “finer-end pressure” mean the tool has applied a hidden multiplier?
No. Application and content only change the interpretation flag. The numeric pitch references remain traceable to published formulas or objective screen-width/resolution math.
Can I order a display from this assessment alone?
No. Final engineering should still confirm exact module/cabinet dimensions, available product pitches, screen height/aspect ratio, structural and service constraints, brightness/environment, control system, budget and actual site geometry.
