How should a business video be?

Why one number never fits

Every guide that hands you a single figure is answering the wrong question. A 12 second clip of a countertop being wiped down and a 9 minute walkthrough of a full bathroom refit are both correct, because they are doing different jobs. Length is a consequence of the goal, not a setting you pick first.

For a local or trades business, three jobs cover almost everything you will film. You want to be found by people scrolling who have never heard of you, you want to teach one useful thing to people who have started paying attention, and you want to be the full answer when someone deliberately searches for the problem you fix. Each job has a natural length, and once you know which job a clip is doing, the length stops being a guess.

Short vertical video, for reach

When the job is reach, shorter wins, because the feed rewards clips that hold attention to the end and then loop. A 15 second clip that most people finish earns far more distribution than a 60 second clip most people abandon, and a short clip has less room to lose anyone. This is the lane for the drone pass over a finished roof, the before and after reveal, the satisfying pressure-wash strip, the one-line myth you hear from customers every week.

Vertical and captioned is the default here, not a nice-to-have. Most people watch on a phone with the sound off, so if the point only lands through audio, it does not land. Burn the captions in, frame it 9:16, and put the most striking second first.

Mid length, for teaching one thing

Once someone is watching your account rather than just passing it, you have earned 30 to 90 seconds to teach them one useful thing. Not five things. One. How to tell when a tap washer has gone, what a fair quote for a boiler service actually includes, the difference between the two lash treatments people always confuse. A single point held tightly at this length builds the quiet authority that makes someone save your number.

The failure mode is padding. If the idea can be said in 40 seconds, stretching it to 80 does not make it more thorough, it makes it easier to leave. Script the one sentence you want the viewer to remember, build the clip backwards from it, and cut everything that is not carrying that sentence.

Long form on YouTube, for high-intent search

The long lane behaves differently from the feed because the viewer arrived on purpose. Someone typing how much does a full rewire cost or why is my heat pump short cycling wants the complete answer, and a thorough 8 to 12 minute video suits them. They are closer to hiring than anyone scrolling a short vertical clip, which is why this content quietly pulls in real enquiries long after it goes up.

This is also where video stops expiring. A short clip does its work in a few days and fades. A search-led explainer keeps surfacing for the same query for months, so the effort compounds instead of resetting. If you only make time for one long video a month, make it the honest answer to the question your customers ask most before they commit.

The first second or two decides everything

Whatever the length, the opening carries more weight than all the rest combined, because that is the moment the viewer decides to stay or scroll on. A slow logo animation, a wind-up, or three seconds of you settling into frame spends the only attention you were given. Lead with the result, the surprising claim, or the moment of change, then earn the rest.

This is why the same 30 second clip can pull a few hundred views or tens of thousands. The footage barely changed. The first second did. Before you worry about the ideal total length, get the first frame and first line right, because a weak opener makes every other length question irrelevant.

Watch-through rate beats raw length

The number that actually drives distribution is not how long your video is, it is what share of it people watch. Platforms read a high completion rate, and the loops that follow it, as proof the clip is worth showing to more people. That reframes the whole question. You are not asking how long you can make this, you are asking how long you can go while most people still finish.

In practice that means cutting to the shortest version that still makes the point, then reading the retention graph the platform gives you. If people drop at the same spot every time, that is where the clip got boring, and trimming to just before it will usually lift reach more than any change to the topic.

Shoot once, cut for each place

The good news for a busy owner is that these lengths are not separate shoots. One thorough job filmed properly becomes a long YouTube explainer and a handful of short vertical clips carved out of the best moments. The full walkthrough answers the searcher, the 15 second reveal from minute six wins reach, and the 60 second how-to from the middle teaches the one thing. Same afternoon of filming, three jobs done.

Film a little more than you think you need, keep the phone vertical or shoot wide enough to crop to vertical later, and capture clean moments you can lift out whole. Then cut long for search and short for the feed. The footage is the raw material, and the length is just how you serve it to each audience.

Common questions

is there one ideal length for a business video?

No, and any figure that claims to be is answering the wrong question. Length follows the job the clip is doing. Aim for 7 to 30 seconds when you want reach, 30 to 90 seconds when you want to teach one thing, and several minutes on YouTube when someone has searched for the full answer.

how long should a video be for instagram reels or tiktok?

Shorter than you think, because the feed rewards clips people finish and then loop. Something in the 7 to 30 second range holds attention best for reach, and pushing past about 90 seconds tends to cost you distribution to people who do not already follow you. Say one thing, cut it tight, and lead with the strongest moment.

how long can a video actually be on each platform?

The ceilings are high and rarely the real limit. YouTube Shorts run up to three minutes, Instagram Reels reach about three minutes for most accounts with longer uploads on some, and TikTok accepts uploads up to an hour. Being able to post 20 minutes to the feed does not mean anyone will watch it, which is why the job, not the ceiling, should set your length.

does a longer video get less reach?

Not because of its length directly, but because longer clips are harder to finish, and a low completion rate is what actually limits reach. A two minute clip most people watch to the end will travel further than a two minute clip most people abandon. Watch your drop-off point and trim to just before people leave.

should i put the same video on youtube and on the feed?

Cut it two ways rather than posting one version everywhere. YouTube suits the full, thorough explainer for people who searched for the answer, while the feed wants a short vertical clip carved from the best moment. One filmed job gives you both, so shoot a little extra and cut long for search, short for reach.

do i need captions and vertical video for a phone clip?

Yes, treat both as the default. Most people watch on a phone with the sound off, so if the point only lands through audio it is lost, and burning the captions in fixes that. Film vertical, or wide enough to crop to a 9:16 frame later, so the clip fills the screen where people are actually watching.
