How many check-in lanes do you need?
Short answer
Size on seconds per person, not headcount. On the day, about 25 seconds each — roughly 140 an hour per lane; the day before, about 40. Check-in the day before: people collecting that day ÷ (90 × hours open). Only 1–2 hours before the start: the 60–70% arriving in the last 30 minutes ÷ 70. A longer morning window: busiest hour ÷ 140, plus one. Add one exception desk, two from about 1,000 attendees.
When does check-in open?
Everyone who needs a badge from this desk, except the groups with their own lanes below.
People who collected their badge at their hotel never join the venue queue.
Usually 60–70% when check-in opens only 1–2 hours before the start. Use last year's figure if you have it.
About 25: 5 seconds to scan and print, 20 for the shortest possible exchange — about 140 people an hour per lane. With badges already printed and nothing said it can fall to 20. Time your own at a rehearsal.
About your event
Day one usually checks in 80% or more; from day two, two general lanes are enough, plus one per group.

10 check-in lanes
650 of 1,000 people (65%) arrive in the last 30 minutes ÷ 72 per lane in 30 minutes, rounded up.
- Plus two exception desks at each point, for wrong details, missing registrations and every other problem. They never take people from the lanes.
- Walk-ups: put up a QR code to register on their own phone. They do not need a lane.
- Staff at the lanes
- 20 · two per lane
- Queue guides
- 2 · head + floating
- Desk length
- 12.0–18.0 m · 1.0–1.5 m a lane
- Power sockets
- 36 · three a lane
Network: a dedicated, symmetric line — about 100 Mbps at a large venue, about 10 Mbps per hotel point.

How the calculator works
- Seconds per person decide everything. About 25 on the conference day: 5 to scan and print the label, 20 for the shortest possible exchange — about 140 people an hour per lane. About 40 the day before, when there is an identity check and a few more words: 90 an hour. With badges pre-printed and nothing said it can fall to 20.
- Check-in the day before: people collecting that day ÷ (90 × hours open). 70% collecting the day before over a two-hour window is the default. For 1,000 attendees that is 700 people ÷ 180 = four lanes; the 300 who come on the day need three.
- Check-in 1–2 hours before the start: last-30-minute arrivals ÷ 70. 60–70% of people arrive in the last thirty minutes — or use last year's figure. One lane checks in about 70 people in half an hour.
- A longer morning window: busiest hour ÷ 140, plus one. Half to two-thirds of same-day arrivals land in the ninety minutes before the opening session, and lanes running flat out have no slack.
- Groups get their own lanes. VIPs with a tiered QR code, exhibitor staff or any group you name are sized separately with the same rule, and keep one lane each on later check-in days.
- Around the lanes: one exception desk per point, two from about 1,000 attendees; two staff per lane, two queue guides per point, 1.0–1.5 metres of desk and three independent power sockets per lane, and a dedicated, symmetric network line.
These are planning starting points, not guarantees. Time your own check-in at a rehearsal on the real venue network three days out, and change the seconds per person to match. The reasoning behind every number is in the on-site check-in field guide.
Frequently asked questions
Divide the people collecting their badge that day by what one lane handles over the hours the desk is open. At about 40 seconds a person a lane checks in 90 an hour, so 700 people over a two-hour window need four lanes. Size the conference-day desk separately for everyone who is left.
Take the 60–70% who arrive in the last thirty minutes and divide by 70 — what one lane checks in in half an hour at 25 seconds a person. For 1,000 attendees that is 650 people and ten lanes. Add an exception desk on top for the unusual cases, two from about 1,000 attendees.
About 140 with two staff, at 25 seconds a person: around 5 seconds to scan and print the label and 20 for the handover and the shortest exchange. The day before, with an identity check, allow about 40 seconds — 90 an hour. Speed comes from the handover, not the scanner, which is why two people per lane beats one person with a faster device.
Because arrivals are never flat. For a morning-start conference, between half and two-thirds of same-day arrivals land in the ninety minutes before the opening session. Desks that are comfortable across a four-hour window collapse in that ninety minutes.
A desk beside the lanes that handles every problem case — a wrong name on a badge, someone not found in the system, a registration still pending approval, someone attending in another person's place — so that one complicated attendee does not stop a lane for four minutes while the queue behind them grows. Set up one, and two from about 1,000 attendees.
Spread the peak rather than absorbing it. Open check-in the day before, or run it at the hotels the evening before, so people arrive already wearing a badge — and shorten the handover: pre-thread lanyards in quiet periods, pre-assemble bags by category, and colour-code badges so nobody makes a decision at the desk.
