Structural Beam Load Calculator vs Deck Joist Spacing Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Structural Beam Load Calculator
Estimate the load-bearing stiffness of a simply supported structural beam based on its span, cross-section, and material. Use this when sizing floor joists, headers, or steel beams for construction projects.
- Answers
- Maximum Uniform Load (lbs/ft)
- Inputs
- Beam Length, Moment of Inertia, Elastic Modulus, Support Type
Deck Joist Spacing Calculator
Calculates the number of joists needed across a deck's width based on the on-center spacing. Use this when planning deck framing to ensure structural adequacy and code compliance.
- Answers
- Number of Joists Needed (joists)
- Inputs
- Deck Width, Joist Size
