DOOH spot length calculator

Three numbers from the media owner and you know how the spot must be built. No login, no data leaves the browser.

What this means for your spot

Message on screen no later than second
s

Passers-by glance mid-spot and look away after two or three seconds. Brand and offer belong in the first half and then stay put.

Cuts at most

Rule of thumb: one cut per two seconds. Nobody reads more from twenty metres.

Plays per hour

How often your creative runs on one screen.

Chance that a passer-by sees the spot
%

Dwell time divided by loop. Below 10 percent means most people never see your spot. Then the first second counts double.

Share of airtime
%

Slot divided by loop.

Rules of thumb from practice, not a measuring instrument. The only real check is the spot on the screen.

Why this is so: how long should a DOOH spot be?
