Offering 15, 30, 45, 60 and 90-minute versions of the same service
How to choose which lengths to offer, price each one, decide whether clients pick the length or you do, and set up separate event types without leaving your diary full of unusable gaps.
Many services do not have one natural length. A first consultation needs longer than a check-in. Some clients want a quick 15-minute question answered; others want a full 90-minute session. Offering several durations of the same service lets clients buy what they need and helps you charge fairly for your time.
Done badly, though, multiple durations confuse clients and chop your day into fragments nobody can book. This guide covers which lengths are worth offering, how to price them, who should choose, how to set them up as separate event types and how to shape availability so short and long appointments sit together sensibly. For the wider picture of presenting services online, see our guide to service booking pages.
Choosing, pricing and setting up appointment lengths
Which lengths are worth offering?
Start from what you actually deliver, not from a tidy list. Most services settle into two or three useful lengths:
- 15 minutes: quick questions, check-ins, short reviews, triage calls. Useful, but easily overused.
- 30 minutes: the workhorse for follow-ups and focused consultations.
- 45 minutes: a good middle option where 30 feels rushed and 60 feels padded.
- 60 minutes: standard sessions and many first appointments.
- 90 minutes: first assessments, intensive sessions or work that needs set-up time with the client present.
If you cannot describe in one sentence what a client gets in each length that they would not get in another, drop that length.
Pricing each length
Pure per-minute pricing is simple but often undercharges short appointments, which still carry fixed costs such as preparation, admin and the gap they leave in your day. Many businesses price short sessions slightly higher per minute and long sessions slightly lower, so the longer option feels like better value. Whatever you choose, show the price clearly next to each length. On Calenix, paid bookings and deposits are available on the Individual plan and above through third-party payment providers such as Stripe; check which payment options are available for your account and region.
Who chooses the length?
There are three common approaches:
- The client chooses from a small menu. Works well when clients understand the difference, such as 30 or 60-minute massages or coaching calls.
- You decide based on the type of visit. A first visit is always 60 or 90 minutes; follow-ups are always 30. Clients choose 'first visit' or 'follow-up', not a number.
- You decide after a short call. For complex work, offer a short consultation, then send the client a link to the length you recommend.
A rule worth adopting: make first visits longer by default. They involve history, questions and setting expectations, and squeezing them into a standard slot tends to make every later session run over.
One event type per duration
The simplest and clearest way to offer several lengths is a separate event type for each, named from the client's side: '30-minute follow-up', '60-minute first consultation'. Each event type then carries its own price, description, booking questions and buffer. Check whether your tool lets one event type offer a choice of lengths; on Calenix, set each length up as its own event type. The Free plan includes one event type, so offering more than one duration needs the Individual plan, which allows unlimited event types.
How durations affect your available slots
Longer appointments mean fewer start times, and mixing lengths creates odd gaps. As illustrative arithmetic, a four-hour morning holds eight 30-minute appointments, four 60-minute ones or two 90-minute ones with an hour spare. Book one 90-minute session at 10am and a 60-minute one at 12:15, and you may be left with a 45-minute gap at 11:30 that only a 30 or 45-minute booking can fill, and a 15-minute sliver nobody can use. Add buffers and the gaps get more awkward.
Why getting durations right pays off
Appointment length is one of the main ways clients judge value. If the only option is 60 minutes when they need 15, they either do not book or feel short-changed. If the only option is 30 minutes and the work needs 60, sessions overrun and your next client waits. Offering the right lengths makes both problems go away.
Durations also shape your income more than most settings do. The mix of short and long appointments decides how many slots you sell, how many awkward gaps you are left with and how much admin each hour of client time carries. Two businesses with the same hourly rate can earn quite differently simply because one offers lengths that fit together and the other does not.
There is a client experience angle too. A short menu of clearly described options is easier to choose from than a long list of near-identical services. Our list of common booking page mistakes includes too many choices for exactly this reason, and making it easier to book appointments starts with a clear choice.
Finally, durations are not set and forget. Once you have a month or two of bookings, the lengths clients actually choose will tell you which options to keep, which to merge and where the price needs adjusting.
What multiple durations give you and your clients
Fairer pricing: clients pay for the time they need, and you are paid for longer work.
More bookings: clients who only need a quick answer will book a short slot rather than nothing.
Better first visits: a longer first appointment gives you time to understand the client properly.
Fewer overruns: appointments are booked at a length that matches the work.
Clearer choices: well-named options help clients pick without emailing to ask.
Useful data: the lengths clients choose show you what to keep and what to drop.
Setting up multiple durations in 7 steps
Pick the service that needs variants — Start with one service where clients genuinely need different lengths, rather than adding durations to everything at once.
Choose two or three lengths — Decide which lengths are genuinely different in what the client gets, and drop any that overlap.
Price each length — Set a price per length, allowing for the fixed cost of short appointments, and decide whether any length needs a deposit.
Decide who picks the length — Let clients choose from a short menu, fix lengths by visit type, or recommend a length after a short call.
Create one event type per length — Name each from the client's side, add a one-line description of what is included, and set its own buffer and booking questions.
Shape availability around the mix — Keep short appointments to set windows where your tool allows it, so they fill gaps instead of breaking up long blocks.
Review the mix after two months — Check which lengths sell, where gaps appear and whether prices need adjusting, then trim the menu.
Appointment lengths at a glance
| Feature | Good for | Pricing approach | Effect on your diary |
|---|---|---|---|
| 15 minutes | Quick questions, check-ins, triage | Higher per minute to cover fixed costs | Fills gaps but can fragment long blocks |
| 30 minutes | Follow-ups, focused sessions | Your standard rate | Fits easily around most other lengths |
| 45 minutes | When 30 is rushed and 60 is padded | Between your 30 and 60 prices | Can leave 15-minute slivers if mixed carelessly |
| 60 minutes | Standard sessions, many first visits | Your standard rate or slightly below per minute | Predictable; easy to plan around |
| 90 minutes | First assessments, intensive work | Slightly lower per minute to reward the longer booking | Uses large blocks; best in set windows |
Tips for a clean duration menu
Offer no more than three lengths of any one service unless clients clearly need more.
Put the length and price in the event type name or first line of its description.
Make first visits longer by default rather than hoping clients will choose the longer option.
Describe what the client gets in each length, not just the number of minutes.
Group short appointments into set windows so they do not split your longer blocks.
Give each length its own buffer; a 90-minute session usually needs more turnaround than a 15-minute call.
Review which lengths sell after two months and remove the ones nobody books.
Common duration mistakes
Offering every length from 15 to 120 minutes and leaving clients unsure which to pick.
Pricing strictly per minute so short appointments barely cover their admin.
Letting first-time clients book a 15-minute slot for work that needs an hour.
Allowing 15-minute bookings at any time, so long sessions can no longer fit in the day.
Naming event types from your side ('Type B session') rather than the client's.
Changing lengths without updating confirmations, descriptions and prices to match.
Example: a dietitian in Coimbatore
A fictional dietitian in Coimbatore sees clients in person on weekday mornings and by video in the evenings. She used to offer one 45-minute appointment for everything. First visits ran over, and returning clients with a quick question paid for time they did not need.
She rebuilt her menu on Calenix's Individual plan with four event types:
- First consultation, 90 minutes: history, food diary review and an initial plan. ₹2,400.
- Follow-up, 45 minutes: progress review and plan changes. ₹1,300.
- Quick check-in, 15 minutes (video only): one question, a recipe swap or a plateau. ₹500.
- Family meal-planning session, 60 minutes: for parents planning meals for children. ₹1,600.
Her website and Instagram bio link to the first consultation; follow-up and check-in links go to existing clients in her after-visit emails. She keeps quick check-ins to a 6pm to 7pm evening video hour, so they never break up her morning clinic. Her clinical notes stay in her own records system, because Calenix is a scheduling tool, not a clinical records system.
The illustrative maths: a three-hour morning previously held four 45-minute appointments at ₹1,300, or ₹5,200. It now typically holds one first consultation and two follow-ups, or ₹5,000, but the first visits no longer overrun, and five evening check-ins a week add ₹2,500 that she was not earning before.
