Sliding Gate Calculator — Calculate Gate Size & Requirements

Sliding Gate Calculator

Calculate sliding gate dimensions, materials, track length, and motor requirements. Determine proper sizing for residential or commercial sliding gates.

Step 1: Gate Specifications

12.0
6.0

Track Length Formula

Track Length = Gate Width × 1.5 + 2 ft (for overtravel)
This ensures the gate can fully open and has space for the motor.

Step 2: Gate Type & Options

Common Gate Sizes

Residential single: 10-14 ft
Residential double: 16-24 ft
Commercial: 20-30 ft
Industrial: 30-50 ft+

Sliding Gate Formulas

Track Length = (Gate Width × 1.5) + 2 feet

Where:
• Gate Width = Width of the gate panel (feet)
• 1.5 multiplier = Space needed for gate to slide open
• +2 feet = Overtravel space for motor mechanism

Weight Calculation:
• Gate Weight = Area × Material Weight per sq ft
• Aluminum: ~4 lbs/sq ft
• Steel: ~6.7 lbs/sq ft
• Wrought Iron: ~10 lbs/sq ft
• Wood: ~3 lbs/sq ft
• Vinyl: ~2 lbs/sq ft

Example Calculation

Example: 12 ft Steel Sliding Gate

Width: 12 feet
Height: 6 feet
Material: Steel (6.7 lbs/sq ft)

Calculations:
Area = 12 × 6 = 72 sq ft
Weight = 72 × 6.7 = 482 lbs
Track Length = (12 × 1.5) + 2 = 20 ft
Motor Power Required: ½ HP (for up to 500 lbs)
