Before the Wedding

The duties of a best man begin well before the tux is rented or the wedding rings are picked up.

Support During the Engagement

The best man often helps organize events leading up to the wedding, such as the engagement party or even helping choose wedding gifts for family and friends. Your role is to keep the groom grounded—and maybe distract him with a few rounds of video games when things get overwhelming.

Help with Planning Logistics

You’re not the wedding planner, but you are a reliable point person for the groom. That includes helping with groomsmen’s fitting, coordinating travel plans for the rest of the wedding party, and making sure everyone sticks to the schedule. It’s also helpful to assist with choosing the right wedding attire, whether that’s tuxedos or more relaxed suits for a destination wedding.

Tip: Always bring extra cufflinks, safety pins, a sewing kit, and a stain remover to any suit fittings or events—just in case.

Planning the Bachelor Party (or Stag Do)

One of the most anticipated best man’s responsibilities? The bachelor party.

This isn’t just about hitting the dance floor or renting a sports car for a wild weekend. It’s about organizing a good time that reflects the groom’s personality. Some grooms want Vegas, others want a quiet cabin weekend. Your job is to set rules (if needed), manage the budget, and make sure everyone has a safe place to stay.

Start planning early, especially during wedding season when venues and rentals book up fast. You’re gonna have to take the reins on organizing, but always keep the groom’s wishes front and center. And of course, make sure you keep the last days of singlehood fun, respectful, and unforgettable.

Rehearsal and Pre-Wedding Events

The wedding rehearsal and rehearsal dinner are great warm-ups to making sure the big day runs smoothly.

Ceremony Rehearsal

During the ceremony rehearsal, you’ll practice walking in, standing at the altar, and escorting key family members like the mother of the bride, if needed. Pay attention! Knowing exactly where to be and when helps avoid chaos on the day of the wedding.

Rehearsal Dinner

Usually hosted by the groom’s family, this is a great opportunity to connect with family members and the rest of the wedding party. A short toast here can set the tone and show your appreciation before the formality of the wedding reception.

Morning of the Wedding

The morning of the wedding can feel like a blur of ties, cologne, and nerves. Your role? Keep things calm, on time, and full of good energy.

Here are some things a best man might be responsible for:

Organize the groom’s items:

Wedding bands, marriage license, marriage certificate, and cufflinks should be in a secure pocket or safely stored.

Be the groom’s emotional support:

Whether he needs a pep talk or just someone to tie his tie, you’re there.

Stick to the timeline:

Coordinate with the photography schedule, help keep the groomsmen moving, and be ready for the photo session.

Manage the emergency kit:

Breath mints, tissues, stain removers, band-aids- you’d be surprised what can save the important day.

Be the Groomsmen’s Go-To (and Gentle Enforcer)

One of the most underrated, but completely essential, best man’s duties is acting as the point person for the rest of the wedding party, especially the groomsmen. Think of yourself as the team captain: your job is to make sure everyone is where they need to be, wearing what they need to wear, and doing what they need to do.

On the day of the wedding, this includes:

Checking arrivals:

Confirming each groomsman has arrived on time, fully dressed, and with all the right pieces (wedding attire, boutonnières, matching socks—you name it).

Handling questions:

Whether it’s confusion about the ceremony rehearsal, suit fittings, or where to meet for the photo session, you’re the guy with the answers (or the one who knows who to ask).

Keeping things smooth

If someone’s tie won’t stay straight, someone else forgot their belt, or someone’s running late, you step in, quickly, calmly, and without bothering the groom.

This is where your group chat skills come in handy. A few well-timed reminders in the days leading up to the wedding (and a few nudges on the morning of the wedding) can save everyone a lot of stress. When the groomsmen look polished, arrive on time, and know where to be, it sets the tone for the rest of the day. And when things go wrong—and they probably will—it’s the best man’s responsibility to quietly manage the moment, so the groom can focus on the joy ahead.

During the Ceremony

As the best man, one of your main roles during the wedding ceremony is to support the groom and hold the wedding rings- arguably the most important task of the day.

You may also:

• Escort key family members (especially if there’s no ring bearer or if the ceremony is more non-traditional).
• Stand beside the groom and keep him cool, calm, and collected.
• Sign the marriage certificate or marriage license as an official witness.

Be present, focused, and ready to offer a reassuring glance or a silent joke when the moment calls for it.

The Best Man’s Speech

Ah, the best man speech—a mix of humor, heart, and maybe a few harmless, not too embarrassing stories. This is your chance to celebrate the groom and the couple. Keep it warm, respectful, and not too long. If you’re nervous, just speak from the heart. Include a few key memories, mention the maid of honor or matron of honor if appropriate, and raise a glass to the celebration of love. And yes, TikTok might immortalize this moment, so make it count.

The Reception Party

At the wedding reception, your job isn’t over—it’s just evolved.

• Help kick off the first dance or get the party started on the dance floor.
• Be the point person for guests who have questions or for the couple when they need someone to handle hiccups.
• Keep an eye on the couple’s needs- refresh their drinks, grab them a plate, or help them make a quick exit in the getaway car at the end of the night.

You may also be involved in handing out party favors, coordinating the groomsmen’s gift, or giving final hugs to out-of-town family members.

After the Wedding

Yes, your role extends a little beyond the last dance. If there’s a brunch the next morning, help with organization. You can also make sure the wedding rings, marriage documents, and any gifts are stored safely. And of course. sssist with returns (like suits or rentals), and check in with the newlyweds to remind them how much fun everyone had.
