# How many iPads and Printers needed for my events? When planning for an event to handle attendee arrivals and access, several factors need to be taken into account: * Maximum concurrent traffic - Determine the maximum number of attendees that will be accessing the platform and checking into the event at the same time during peak periods. For example, if the doors open at 9 am and there is a rush of attendees between 9-10 am, how many attendees are predicted to check-in during that busiest hour. * Recommended capacity - As a general rule of thumb, most event we recommend provisioning 1 all-in-one box for every **500 attendees** concurrently. So you would need 4 boxes to handle 2,000 attendees checking in during the busiest part of the day. * Total daily attendee volume - Consider the total number of expected attendees over the course of the full event day, not just peak periods. For example, if you have 20,000 attendees total over 12 hours from 9 am to 9 pm, a large portion may arrive during off-peak hours with smaller surges spread throughout the day. * 1 all-in-one box contains 4 iPads + 2 Printers. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
