Choosing the correct truss size is one of the most important steps in building a safe and professional stage or event structure. Whether for concerts, exhibitions, weddings, outdoor festivals, or LED screen installations, the right truss dimensions directly affect stability, load capacity, and overall project safety.
This TOURGO guide will help you understand how to select the most suitable aluminum truss size for different applications.
Why Truss Size Matters
- capacity
- Span distance
- Structural stability
- Wind resistance
- Compatibility with lighting and LED equipment
Choosing a truss that is too small may lead to structural risks, while oversized trusses can increase transportation and project costs unnecessarily.

| 6–10m | 290×290mm |
| 10–16m | 400×400mm |
| 16m+ | Heavy-Duty Truss |
3. Indoor or Outdoor Use
Outdoor applications require:
- Stronger truss systems
- Better wind resistance
- More stable support structures
For outdoor concerts and festivals, larger trusses are generally recommended.
4. Event Type
| Event Type | Recommended Truss |
|---|---|
| Exhibition Booth | 200×200mm |
| Wedding Stage | 290×290mm |
