Pet Gates and Playpens: Opening Width, Height and Fixing Type

Black mesh pet playpen with a gated opening

Pet gates and playpens should suit the animal, opening and mounting surface. A pet product is not automatically a child-safety gate, even when the designs look similar.

Measure the complete opening

Record width at the specified fixing points, skirting-board projections and any uneven surfaces. Check the product's supported width range and approved extensions. For a pen, draw the assembled shape and gate swing on the floor.

Detail What to compare
Height and spacing Suitability for the animal's size and behaviour
Fixing type Pressure, wall fixing or freestanding arrangement as documented
Door Usable opening and latch operation
Surface Stable support and permitted indoor or outdoor use

Consider how the animal behaves

A gate that physically fits may not contain an animal that climbs, jumps or pushes against it. Use the product only for its intended purpose and inspect the setup regularly. Do not improvise extensions or rely on furniture to support an unsuitable panel. Keep food, water, resting space and supervision appropriate to the use of a pen. Choose a complete compatible system rather than combining unrelated panels because their heights are similar.

Test the full opening

An opening can have different widths at floor level, above a skirting board and at the intended top fixing. Record each relevant measurement and compare it with the gate's mounting instructions. Include the space needed for its door to swing. For a playpen, draw the assembled shape rather than multiplying a panel width by its panel count; corners and connectors change the usable area.
