Built for a room full of momentum.

Start from the ceiling rather than the design. Three of the four sizes stand 81 inches tall, which is 6 feet 9 inches of panel, and the 24 by 62 inch option is the one that fits under a low reception soffit or a dropped ceiling. Measure at the spot the banner will actually live, since ductwork and sprinkler heads hang lower than the roof. Width matters too, because the base sits on floor a class may be using.

These are built for indoor use. Wind is hard on a retractable mechanism, and a gust that tips a loaded base in a sidewalk is a hazard as well as a repair. If you want to catch foot traffic outside a strip plaza unit, use an outdoor rated format instead and keep the retractable for the lobby, the class floor and the event table at expos and open days.

On the wall members face while they wait, not the wall they face while they train. A schedule is read standing still, in the two minutes before a class starts, which usually means the corridor, the changing room door or the wall beside the water station. Avoid the mirror wall and anything directly across from it, because a laminated sheet under a light panel reads as a bright rectangle from the back of the room. Check the sheet from the floor at the far corner before you commit to a size.

You can, and then you have to honor it. A price, a term or a cancellation promise on a poster at the desk is read as the offer, and the agreement a member signs has to match it. Several states regulate health club contracts directly, including how the cancellation notice must appear, and some require registration or bonding as well. The practical answer is to print what does not move, such as the class timetable and what a first visit includes, and keep prices and terms on the paperwork you can revise without a reprint.
