A gate must suit both the opening and the animal. Begin with the location, including nearby stairs, uneven trim and the route people use through it.

Measure the complete opening

Measure at the intended upper and lower contact points. Note skirting boards, sloping floors and nearby door swings. Compare the full installed width with the manufacturer’s approved extensions; improvised spacers are not a reliable way to make a gate fit. Check that the latch can operate without hitting furniture.

Choose mounting for the location

Follow the exact installation instructions and required wall or frame fixings. Do not use a pressure-mounted gate at the top of stairs. A label describing a product as suitable for pets does not establish suitability for every stair location. If the structure cannot support the required installation, choose another location or barrier arrangement.

Assess the animal rather than height alone

Look at bar spacing, lower gaps and footholds as well as overall height. A small animal may squeeze through while an agile one climbs over. Never test containment by leaving a distressed pet alone behind a new barrier. Observe the first uses and keep a secure alternative available if the animal pushes, climbs or becomes caught.

Rehearse ordinary passage

Open, close and verify the latch repeatedly with the pet away from the opening. Check whether a threshold is an awkward trip point. Explain operation to visitors and caregivers. Recheck mounting after impacts or nearby floor work. A barrier people routinely leave unlatched is not working as intended, even if its dimensions look ideal.
