Measuring for a made-to-measure sliding patio door: what to confirm before ordering

A made-to-measure sliding patio door starts with the opening, but the figure you order is the outside frame size. Before entering measurements, agree the finished width and height with the person fitting the door. This guide uses the options on Swift Aluminium’s live sliding door product pages so you can prepare the right questions.

Start with the finished frame size

Record the required outside frame width and height in millimetres. Check the opening at more than one point and ask your installer which finished size will leave the appropriate fitting allowance for your particular opening. Do not order directly from a rough opening measurement without that check.

The two-pane aluminium sliding patio door configurator specifically says to include the cill in the overall height. Its cill choices include no cill and several cill profiles. Decide which option your installation needs before confirming the order height; ask your installer if you are unsure.

Decide the layout while you measure

Measurements alone do not describe how the door will work. On the two-pane aluminium product, the master sliding door is selected as viewed from outside: left hand or right hand. There is also a choice for both doors to slide. Stand outside the opening with your installer and confirm the movement you want, including where furniture and the walking route will be.

If a two-pane arrangement does not suit the opening, compare Swift’s three-pane, four-pane and triple-track options. Each has its own live configurator. Choose the product that matches the intended arrangement before entering sizes; do not assume options or permitted dimensions transfer between products.

Check the finish and fitting details

The two-pane aluminium product lets you choose external and internal colours, a cill and a handle colour. Review the complete selection and live price after entering your dimensions. If the doors are part of a wider project, confirm with your installer how the frame, cill and surrounding finish will meet.

Pre-order checklist

• Have the installer confirm the outside frame width and height in millimetres.
• Confirm whether a cill is needed and whether its height is included in the ordered height.
• Choose the pane and track arrangement from the product actually being ordered.
• Confirm the sliding side from the outside-view perspective where the configurator uses it.
• Check colour, handle and other selected options, then review the final configuration and price.
• Read the shipping policy and returns terms for made-to-measure products before checkout.
