Metal grandstand simulator
Metal grandstand simulator: rows, seats, height and length
Enter the required number of seats, the required height or number of tiers, the tread, riser and seat dimensions and the available length. The simulator calculates rows, seats per row, overall length, depth and height, and draws a side section and a plan view. Results are estimates for an early study.
- Resulting seats
- Seats per row
- Rows
- Seats above requirement
- Overall length
- Top tier height
- Overall height with rail
- Overall depth
- Rake angle
- Footprint
Side section
Plan view
These are estimates for an early study only. Default values are editable and are not regulatory requirements. The structural design of the steel frame, foundations and loads, stair and exit widths and guardrail height are set in the detailed design under the code that applies at the project site.
Send these figures with a grandstand study requestHow it is calculated
- By height: rows = floor((required height − first tier height) ÷ riser) + 1.
- By tiers: top tier height = first tier height + (rows − 1) × riser.
- Seats per row = ceil(required seats ÷ rows); resulting seats = seats per row × rows.
- Overall length = seats per row × seat width + aisles × aisle width.
- Overall depth = rows × tread; overall height = top tier height + guardrail height; rake angle = atan(riser ÷ tread).
- If the overall length exceeds the available length: seats that fit per row = floor((available length − aisles) ÷ seat width), and the rows needed and their height are shown.
