How many QR codes does a gym actually need?

Five cover everything: class booking at the desk, membership signup on flyers, Wi-Fi in the locker room, Google reviews at the exit, and the waiver or health form. More than that and members stop noticing any of them.

Should the class-schedule code be static or dynamic?

Dynamic. The timetable changes with seasons, holidays and instructor availability. A dynamic code lets you update the linked schedule from the dashboard without reprinting the desk sign.

Where is the best spot for a Google review code in a gym?

On the exit door or next to the mirrors, where members pass right after the workout. Link it to the direct review form, not your business profile, so the review is one tap away.

How big should a gym QR code be printed?

Match the reading distance: 25 mm at arm's length at the desk, 35 mm at one metre in the locker room, 60 mm for an entrance poster, 90 mm for a street-facing window.

How do I protect printed codes from sweat and cleaning spray?

Laminate paper codes or print on vinyl, and prefer matte surfaces — glossy laminates and mirrors reflect light into the camera and cause scan failures.

QR codes for gyms, studios and salons

Updated September 20, 20267 min read

In a gym, studio or salon the phone is already in the member's hand — on the treadmill, between sets, at the checkout. A QR code works here better than almost anywhere else, but only if each code does exactly one job and sits exactly where that job happens. Five codes cover the whole business; everything beyond that is decoration nobody scans.

The five codes that earn their wall space

Resist the urge to print a code for everything. Each code below has a moment attached to it — a second where the member is standing still, phone in hand, with a reason to scan. That moment is what makes a code get used.

The five spots where a code earns its place
Where	The code opens	Static or dynamic
Front desk	Class schedule and booking	Dynamic — the timetable changes with the seasons
Trial-pass flyer	Membership signup page	Dynamic — swap the offer without reprinting
Locker room wall	Wi-Fi network	Static — the password rarely changes
Exit door, mirrors	Google review form	Dynamic — reviews are a campaign, and you want the count
Welcome email, printed card	Waiver or health form (PDF)	Dynamic — the form gets updated every year

The review code: timing beats placement

The best moment for a Google review is the walk out — the workout is done, the endorphins are high, and the phone comes out anyway. A code on the exit door or next to the mirrors catches exactly that window. Print it with the direct review link so the scan lands inside the review form, not on your business profile.

Make this one dynamic and check its scan count once a month. If the code gets scans but reviews do not move, the problem is the link, not the wall — you can fix it from the dashboard without touching the print.

The Wi-Fi code: the quiet workhorse

The locker room is where members sit down with their phones — and where mobile signal is usually worst. A Wi-Fi code on the wall connects them in one scan, no password typing, no staff interruptions. This one can be static: the network password changes rarely, and a static code is free and unlimited.

Print it big enough to read from the bench — 35 mm at one metre — and laminate it. Steam and cleaning spray will destroy an unprotected paper code within weeks.

Print sizes that match the room

Print width by real reading distance
Spot	Typical distance	Minimum width
Table card at the desk	Arm's length	25 mm
Locker room, mirror	1 m	35 mm
Poster at the entrance	2–3 m	60 mm
Window facing the street	3–5 m	90 mm

Mirrors and glass reflect — print window codes on matte vinyl, not glossy. And test every code at the real distance under the real lighting: a gym at 7 a.m. is dimmer than your desk.

Measure it, or it is decoration

With dynamic codes every scan is counted — by day, by hour, by city. After a month you will see which wall works and which does not. Move the booking code if the exit code outperforms it; drop a code that nobody scans. The dashboard answers these questions in seconds, and the printed image never has to change.
