How to Make a Sign-Up Sheet in Google Forms
To make a sign-up sheet in Google Forms, add a short-answer question for the person's name, a multiple-choice or dropdown question listing your available time slots, and turn on email collection so you can send confirmations. Share the form link, and every choice lands in a linked Google Sheet you can sort. That gives you a working sign-up sheet in about five minutes, and it is free.
The one thing to know before you start: Google Forms will not stop two people from picking the same slot, and it cannot hide a slot once it is full. There is no native "limit to 10 per option" setting. This guide walks through building the sheet, adding time slots, collecting emails, and closing the form when you are full, and it is honest about the workarounds for that capacity limit so you do not get surprised on the day of the event.
Build the sign-up sheet, step by step
- Go to Google Forms and start a Blank form. Give it a clear title like "Parent-Teacher Conference Sign-Up" and a short description with the date and any instructions.
- Add a Short answer question for Full name. Click the three-dot menu on that question and turn on Required so no one submits a blank entry.
- Add a second question for the time slot. Choose Multiple choice or Dropdown as the question type, then type each slot as its own option: "Monday 3:00 PM", "Monday 3:15 PM", "Monday 3:30 PM", and so on. Mark this question Required too.
- Add any other fields you need, such as Phone number or Student name, as short-answer questions.
- Click Send, copy the link, and share it. Responses collect automatically.
That is the whole build. Multiple choice and dropdown behave the same way for the person signing up; dropdown just saves vertical space when you have a long list of slots.
Adding time slots people can pick
Time slots are just the options on your multiple choice or dropdown question. Two things make them work better:
- Write slots so they sort cleanly in the sheet. If you use a 24-hour style or a consistent "Day HH:MM" format, the linked Google Sheet sorts them in order instead of scattering them. "Tuesday 09:00" and "Tuesday 14:00" line up correctly; "Tuesday 9am" and "Tuesday 2pm" may not.
- Put the date in the question, not every option. If the whole event is one day, say the date once in the question text and keep each option to just the time. Shorter options are easier to read on a phone.
If you want people to sign up for more than one slot (say, a volunteer picking several shifts), use the Checkboxes question type instead so they can select multiple. Just know that one person can then take several slots at once.
The big limitation: Google Forms cannot cap sign-ups per slot
This is the part that catches people, so here it is plainly. Google Forms has no built-in way to:
- Limit a time slot to a set number of people.
- Remove or gray out a slot once it is full.
- Stop two people from choosing the exact same slot.
The form will happily accept ten sign-ups for a slot meant for one. There are three honest ways people work around this, and none of them is perfect:
- Watch the responses and edit options manually. Keep the linked sheet open, and when a slot fills, open the form and delete that option from the question. Anyone who loads the form after that will not see it. The catch: people who already have the form open still see the old list, so you can still get a double-booking in the gap.
- Overbook on purpose and sort it out. For low-stakes sign-ups, let people pick freely, then reassign duplicates by email afterward. Simple, but it means follow-up work.
- Use a Forms add-on. Add-ons like Choice Eliminator or FormLimiter can auto-remove a full option or close the form at a response cap. To be clear about what these are: they are third-party tools you install from the Google Workspace Marketplace, not a Google feature, and they run on your account with permission to your form data. They can work well, but vet any add-on before installing it, and know that free tiers often have limits.
If per-slot capacity is critical, such as booking equipment or one-on-one appointments where a double-booking is a real problem, a purpose-built scheduling tool that enforces capacity will save you the manual babysitting. For a casual class or event sign-up, the manual approach is usually fine.
Collect emails so you can send confirmations
To email people back, you need their address on file:
- Open Settings at the top of the form.
- Under the Responses section, find Collect email addresses and set it to Verified (for signed-in Google users) or Responder input (they type it in).
- Optionally turn on Send responders a copy of their response so each person automatically gets a receipt of what slot they chose.
With emails collected, you can also message everyone in a slot at once later, for example to send a reminder or a room change, by copying the addresses from the linked sheet.
Close the form when you are full
When every slot is taken, stop accepting responses so no one signs up for a full event:
- Open the form and click the Responses tab.
- Toggle Accepting responses off.
Anyone who opens the link after that sees a "no longer accepting responses" message. You can customize that message to point people to a waitlist or a next date. For a fuller walkthrough, including how to reopen it and how to schedule the close, see our guide on how to close a Google Form.
Share by link or QR code
A plain link works for email and messaging apps. For anything physical, a printed flyer, a classroom door, a table at an event, a QR code is faster because people just scan and open the form on their phone. You can turn your form link into a scannable code for free with the Google Form QR code generator, then drop it on your printout. No app or account needed to scan it.
Quick answers
Can Google Forms limit how many people sign up for one time slot? No, not on its own. There is no native per-option cap. You either edit the options manually as slots fill, watch for duplicates, or install a third-party add-on that removes full options.
How do I make a time slot dropdown in Google Forms? Add a question, set its type to Dropdown or Multiple choice, and type each time slot as a separate option. Mark the question required so no one skips it.
Can I let people pick more than one slot? Yes, use the Checkboxes question type instead of multiple choice. That lets one person select several options at once.
How do people get a confirmation after signing up? Turn on Collect email addresses in Settings, then enable Send responders a copy of their response. Each person gets an automatic receipt of their choice.
Where do the sign-ups go? Into the form's Responses tab, and into a linked Google Sheet if you connect one. From the sheet you can sort by time slot and spot duplicates.
Is there a Google Forms sign-up sheet template? Google's own template gallery includes event and RSVP templates you can adapt, but the fastest route is usually building the two-question form above from a blank form. It takes about the same time and fits your slots exactly.

The bottom line
A Google Forms sign-up sheet is quick, free, and good enough for most classroom and event sign-ups: one name question, one time-slot question, email collection on, and close the form when you fill up. The single thing to plan around is capacity, because Forms will not enforce it for you. For low-stakes sign-ups, watch the sheet and edit options as needed. For anything where a double-booking really hurts, use an add-on that caps responses or a dedicated scheduler. Print a QR code next to the link and people can sign up from their phones the moment they see it.
