Duration
Length of session, exercises & how to track time
Duration online is not just the total time on the calendar; it is how you slice that time into segments the group can actually sustain attention through.
People on a screen have a shorter focus window than people in a room. Research and facilitator experience consistently point to 45 to 90 minutes as the outer range for a single focused online working block before attention degrades. Beyond that, breaks are not a luxury but a structural necessity.
Duration decisions include the total length of the session, the length of individual activities and segments within it, and where breaks sit. A two-hour session online is not the same as a two-hour session in a room: it needs more breaks, shorter segments, and more frequent mode changes to hold the same quality of participation.
Track time visibly during the session. A clock running only in your window is an invisible constraint. When participants can see how much time is left on an activity, they pace themselves and you can hold the group without repeatedly announcing it.
