What Pet Gate Size Do I Need?
Use your measurements for opening width, required barrier height, and candidate gate minimum width to find pet gate fit.
Enter your measurements
For what pet gate size do i need, use the real measurements for opening width, required barrier height, and candidate gate minimum width. The calculator then reports pet gate fit and keeps any manufacturer- or rule-specific checks separate.
- Opening width — Required
- Required barrier height — Required
- Candidate gate minimum width — Required
- Candidate gate maximum width — Required
- Candidate gate height — Required
Pet gate fit
Enter the measurements above to calculate pet gate fit.
How the calculation works
V12 calculation: widthPass=gateMinWidth≤openingWidth≤gateMaxWidth; heightPass=gateHeight≥openingHeight; overallPass=widthPass AND heightPass. This is the implementation specification for this calculator.
Worked example
Example: Opening width = 90 cm; Required barrier height = 90 cm; Candidate gate minimum width = 75 cm; Candidate gate maximum width = 100 cm; Candidate gate height = 95 cm. Result: Fits; Height Pass = Pass; Width Pass = Pass.
Before you decide
Use measured dimensions rather than nominal labels. This page calculates the stated geometry or quantity only; product-specific construction or installation details can still affect the final choice. For what pet gate size do i need, the limiting result on this page is pet gate fit.
Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
Frequently asked questions
What does the Pet Gate Size calculator tell me?
It returns pet gate fit from the measurements entered on this page. The calculation is specific to pet gate size, so the result should be compared with the exact product or specification you are considering.
Which measurements should I take for pet gate size?
Measure opening width, required barrier height, candidate gate minimum width, candidate gate maximum width, candidate gate height. Use clear, usable dimensions rather than nominal room or product labels.
Should I round the pet gate fit?
Keep the calculated value for comparison, then choose a real product that meets or stays within the returned pet gate fit while allowing for the clearances, tolerances or ratings shown by its manufacturer.
