How do I size a Juliet balcony railing?

Measure the clear width of the opening between the reveals and the height from the finished floor, then tell us the railing height required for your building. The wall build-up matters just as much: on an uninsulated wall the balcony fixes on plates in front of the facade, and on an insulated wall on stand-off brackets anchored into the masonry behind the insulation, so tell us the insulation and render thickness. Add a photo of the window from outside and we will adapt our 1500 x 1100 mm starting size to your opening. Use the Juliet-balcony checklist.
