Dwell time benchmarks across salon formats

Dwell time is the metric that makes beauty DOOH different. A roadside billboard is seen for a second or two; a salon client is seated for the length of an appointment. That gap changes how the inventory should be counted and valued — but only if you define dwell properly and resist inventing numbers nobody has measured.

What “dwell time” actually means

Before any benchmark, the definition. The Media Rating Council’s Out-of-Home Measurement Standards (Phase 1 Final, April 2024; combined final, December 2025) define dwell time as “the length of time spent by an individual or the audience in the Display Exposure Zone” — the physical area, also called the viewshed, where a person has the opportunity to see (or hear) a screen (MRC).

Two consequences flow from that definition, and they are why dwell matters commercially:

1. Dwell governs impression counting. Per the MRC, “an ad must run at least one time during the Dwell Time … to be exposed and projected to 100% of the Display impression counts” — otherwise the impression estimate is fractionalised (MRC). A longer dwell window means more of a screen’s loop plays out in front of the viewer, so more ad exposures can be credited per visit.
2. There is a minimum viewable duration. For an out-of-home impression to count as a viewable opportunity-to-see, the ad must hold 100% of pixels on-screen for one continuous second (static) or two seconds (video) (MRC).

So dwell isn’t a vanity number — it’s the variable that decides how many countable impressions a single screen produces.

The dwell window by format

Here is where honesty matters. There is no published, measured dataset of in-venue dwell for beauty DOOH screens — not from us, not from the operators. What is knowable is how long the appointments themselves run, and in a salon the client is captive for essentially the whole service. So the service duration is the dwell-window proxy — clearly a proxy, not a measured screen-dwell figure.

Typical appointment lengths — the booking-slot durations salons schedule — look roughly like this:

Format	Typical appointment length	Note
Waiting / reception	~5–15 min	High churn, brief, peripheral
Barber / men’s cut	~30–45 min	Seated, facing mirror
Hair / styling chair	~45–60 min	Cut & style, captive
Nail bar	~45–90 min	Hands occupied, eyes free
Spa / facial / treatment	~60–90 min	Long, but often eyes-closed
Hair colour / highlights / balayage	~2–3 hours	Longest captive window

(Ranges are typical industry service durations, not measured dwell — see methodology.)

The pattern is the point: even the shortest seated beauty service runs an order of magnitude longer than a roadside or transit screen’s exposure. The waiting area is the one short, high-churn window; the chair is where the minutes accumulate.

Long dwell changes the inventory — within limits

A multi-minute dwell window does two things a billboard-second cannot. It lets a single screen credit multiple full impressions per visit (the loop plays several times within the dwell), and it makes room for sequenced creative — a story across spots, not one frame glimpsed in passing.

But two honest limits keep this from becoming a fairy tale:

• Dwell is not attention. Being in the Display Exposure Zone for an hour doesn’t mean an hour of looking — a spa client may have eyes closed, a nail client may be on their phone. Attention is a separate, smaller quantity layered on top of dwell. (We unpack the attention-seconds that move recall, consideration and intent in Mirror displays vs. lobby screens.)
• Position matters more than raw minutes. A bezel-free screen in the styling mirror — in the client’s forced line of sight — converts dwell into attention far better than one off to the side. Long dwell is the opportunity; placement decides how much is realised.
