Open vs. Invitational Golf: What the Difference Means

An open golf tournament lets any golfer who meets the published rules try to get in. An invitational starts with a selected field: players the host invites, or players who meet preset criteria. That's the whole difference. It is about who gets to enter, not how good the golf is or how famous the event is.

If you're a fan, this guide clears up the terms. If you're organizing your own event, it helps you pick the right label and the right setup. We cover both below.

TL;DR

Open means eligible golfers can apply or register, often through qualifying. Invitational means the host picks the field or sets criteria that grant a spot.
"Open" rarely means anyone can walk up. Age limits, handicap caps, entry fees and qualifying rounds still apply.
Modern pro invitationals often mix personal invitations with objective criteria like rankings and prior wins.
For your own outing, choose open if you want a bigger turnout and invitational if you want control over who plays.
Whichever you choose, publish your eligibility and handicap rules before registration opens.

What "open" means in golf

Generally, an open tournament is open to all golfers, as opposed to being restricted to certain players, like a tour event or an amateur championship. In practice, that means professionals and amateurs can both compete. The U.S. Open and The Open Championship are the standard examples.

But "open" has fine print. Entry is open to anyone who meets the event's published requirements and, where required, advances through qualifying. Think of it as an open door with a checklist beside it.

A real example: the U.S. Senior Open

The 2026 U.S. Senior Open shows how specific an open can be:

Players had to be at least 50 by July 2, 2026.
Amateurs needed a Handicap Index of 2.4 or lower.
Anyone not exempt had to go through qualifying.
The field was 156 players, chosen from 2,780 entries across 31 local-qualifying sites and 12 final-qualifying sites.

That is a very open process, and still a very narrow door. Nearly 2,800 golfers entered for 156 spots.

What "invitational" means in golf

An invitational is a tournament limited to golfers who were issued an invitation, or who met preset criteria that earned one. There is no general public route in. Someone, whether a committee, a host or a set of rules, decides who plays.

The Masters is the classic example. You can't enter it by registering and qualifying locally. You get in by meeting the criteria the club has set, or by being invited.

Pro invitationals aren't just personal invites

The line gets blurry at the top of the game. In 2026, the PGA TOUR ran eight Signature Events: limited-field events with $20 million purses and 700 FedExCup points for the winner. Eligibility came from categories such as the prior-season top 50, the Aon Next 10, the Aon Swing 5, current-year winners and specified ranking categories.

So even a limited-field event with "Invitational" in its name can run on objective rules. The field is concentrated around defined categories instead of an open application pool.

Open vs. invitational at a glance

	Open	Invitational
Who can enter	Anyone who meets published rules	Players the host invites or who meet preset criteria
How you get in	Register, often qualify	Be invited or earn automatic eligibility
Field size	Usually larger	Usually smaller
Feel	Bigger, more anonymous	Smaller, more familiar
Host's control	Set rules, not names	Set rules and names
Typical small-event use	Public charity outings, club championships	Member-guest, corporate, sponsor and friends events
Admin work	More registrations to process	A defined list to manage

Neither is better. They solve different problems.

Why the label matters for your own event

Outside the pro tours, the words work the same way. A small charity event can be open if anyone who meets its rules may register. It can be invitational if the committee selects teams, sponsors, members or guests. The useful question is always: who can earn a place?

Getting this wrong causes real headaches. If you call an event open and then turn people away, you create hard feelings. If you call it invitational and let anyone sign up, you lose the exclusivity that was the point.

Choose open when

You want to raise as much money as possible and need a big field.
You're running a fundraiser for the whole community.
You don't have a defined list of players yet.
You want to promote the event publicly.

Choose invitational when

You're hosting sponsors, clients, members or guests.
You have a limited number of tee times or a small course booked.
You want a field of similar ability or a familiar crowd.
You want to control pace of play and the day's atmosphere.

Or mix them

Many organizers do both. They invite a core group (sponsors, board members, past champions) and open the remaining spots to the public. Just say so plainly in your announcement.

Perspective: what we see from organizers

We built Chase Birdies for individual organizers, not big facilities. Small clubs, casual outings and nonprofit fundraisers are who we think about every day. Here's our honest view of the open versus invitational question.

First, the label matters less than the clarity. Most confusion at small events doesn't come from choosing the wrong type. It comes from not saying who is eligible, whether handicaps are required, and what format you're playing. Put those three things in writing before anyone registers.

Second, an invitational is often easier to run, and an open is often easier to grow. A list of 40 invited players is simple to manage. A public open can bring surprises on the day, like players you've never met and handicaps you can't verify.

Third, scoring shouldn't be the thing that holds you back from going open. Players or scorers enter scores hole by hole from any device, with no app download or registration, and the leaderboard updates instantly. Whether your field is 12 invited friends or 120 public entrants, you don't need to babysit the scoring. Pricing is a flat $1 per player, so a bigger open field costs a predictable amount.

How to set eligibility rules for your event

Publish your rules before registration. The U.S. Senior Open example above shows the model: age, handicap, qualifying and exemptions, all stated up front. Your version can be much simpler.

Decide who is allowed to play. Write one sentence. "Open to all adult golfers" or "By invitation only: sponsors and board members." Be specific about age, membership or team requirements.
State your handicap policy. The USGA's Rules of Handicapping are part of the World Handicap System, which is designed to let golfers compete fairly with one another. For a casual event, say whether handicaps are required, optional, or used only for net prizes. If you need a primer, see our guide on golf tournament handicaps you can automate.
Cap the field. Know how many players your course and tee times can handle. Close registration when you hit the cap, or keep a waitlist.
Set how you'll handle entries. Open events need a public sign-up page and a deadline. Invitationals need a guest list, an RSVP date and a plan for declines.
Choose your format. Scramble, shamble, scotch, best ball, stroke play and match play all work for either type. A scramble is the friendliest choice for a wide-open charity field because every skill level contributes. Our charity scramble how-to walks through it.
Explain prizes. If you award net prizes, say how scores are converted. Our net vs. gross scoring examples show it with real numbers.

Apply entry rules at the club level

Entry rules aren't only for pro events. Clubs apply them every week to tee times, guests and member access. If you run member events or share a course with other groups, it helps to see how clubs handle guest booking controls and club-set booking rules. The same thinking applies to your event: decide who can book, how many guests they can bring and what limits apply.

Other terms you'll hear

Closed tournament

A closed event is the opposite of open. It's restricted to a defined group, such as members of one club or employees of one company.

Opposite-field event

When a pro tour schedules two tournaments on the same dates, the lesser of the two is called an opposite-field tournament. It's a scheduling term, not an entry category.

Major championships

Two of the four majors, the U.S. Open and The Open Championship, carry "Open" in the name and use qualifying. The Masters and the PGA Championship are different routes in. The name tells you the entry path, not the importance.

Running scoring for either type

Whichever type you pick, the scoring job is the same: get accurate scores in, rank players fast, and show everyone where they stand.

With our hole-by-hole scoring, players or designated scorers enter each hole as they go, and scorecards stay editable if someone makes a mistake. The live leaderboard updates instantly. You can make it public for an open event, or protect it with a PIN for an invitational where results are just for the field.

Setup takes minutes, and pricing is $1 per player per tournament, with no subscription or hidden fees. A 72-player outing costs $72. You pay before the event goes live, and that's it.

If you're new to organizing, start with our step-by-step guide to running a golf tournament. Fundraising? Use the charity golf tournament checklist and the budget template. For stroke play events, our stroke play scoring guide helps prevent scorecard errors.

A quick example: one charity event, two versions

Say a youth sports booster club wants a fundraiser at a local course with room for 100 players.

Open version. The club posts a public sign-up, caps the field at 100, sets a $125 entry and says handicaps are optional. A scramble keeps it friendly. The leaderboard is public so families can follow along. Cost for scoring: $100.

Invitational version. The club invites 25 local businesses to enter a team of four. Each team is by invitation, and sponsors get the first call. The leaderboard is PIN-protected and shared with participants. Cost for scoring: $100.

Both work. The first maximizes reach. The second maximizes sponsor relationships. The dollar figures for entry are illustrative, not a recommendation.

Common mistakes to avoid

Calling it open, then limiting it. If you have only 40 spots, say "limited field, first come first served."
Skipping the handicap rule. Players will ask. Answer it on the registration page.
Mixing formats without explaining them. A shamble or scotch event needs a one-line explanation.
Waiting until the day to set up scoring. Create the event, add players and check the leaderboard a few days ahead.
Ignoring match play handicap rules. If you run match play, check our match play handicap guide.

FAQ

What is the difference between an open and an invitational?

In an open, any golfer who meets the published eligibility rules can enter, sometimes after qualifying. In an invitational, the host or a set of preset criteria decides who plays. Open is about access. Invitational is about selection.

Is an open tournament really open to everyone?

Not literally. Open events usually have rules about age, handicap, entry fees or qualifying. The 2026 U.S. Senior Open, for example, required players to be 50 or older and set a 2.4 Handicap Index limit for amateurs.

Can an invitational have qualifying?

Yes. PGA TOUR Signature Events in 2026 used categories like prior-season top-50 status and current-year winners. The field is limited and invited by rule, rather than open to public entry.

Which is better for a charity golf outing?

It depends on your goal. An open event usually draws a larger field and more entry revenue. An invitational works well when you're hosting sponsors, clients or members and want control over the field.

Can I use the same scoring setup for either type?

Yes. With Chase Birdies you can run a public leaderboard for an open or a PIN-protected one for an invitational, at $1 per player.
