Deck Beam Calculator
Calculate proper deck beam sizes for your construction project. Determine beam span, sizing, and load capacity for safe deck design.
Step 1: Deck Dimensions
Understanding Beam Spans
Beam span is the distance between supports. Longer spans require larger beams or closer support spacing. Always check local building codes for specific requirements.
Step 2: Beam Specifications
About Beam Sizing
Beam size is determined by span, load, and material strength. Larger decks and heavier loads require thicker and deeper beams to prevent sagging or failure.

Span Capacity Analysis
Beam Sizing Formula
Beam Capacity = (Material Strength × Section Modulus) / Safety Factor
The beam capacity is calculated based on material bending strength, cross-sectional properties, and required safety factors. Always consult local building codes for specific requirements.
