How often to post on each platform, and the cadence trap

The honest answer to "how often should I post" is another question: for how long can you keep it up? Because the benchmark is easy to look up and almost nobody's real problem.

Here are the 2026 numbers, and then the arithmetic that nobody puts next to them.

The benchmarks#

On Instagram specifically, three to five posts a week — reels, carousels or stills — is described as the sweet spot for reach per unit of effort.

Now add it up#

Run every one of those at the low end and you are publishing about 45 pieces a week. At the high end it is closer to 90.

That is not a content calendar. That is a staffed content team, and pretending otherwise is how a strategy document becomes a source of guilt by week three.

The failure mode is predictable and I have watched it repeatedly:

1. New strategy, every platform at benchmark cadence.
2. Two good weeks.
3. A launch, a holiday, an outage, a flu.
4. Nothing for eleven days.
5. Quiet abandonment, and a set of accounts that now look neglected rather than absent.

An account that posted twice a week for a year is in a materially better position than one that posted forty times in a fortnight and then stopped. Both the ranking systems and the humans read consistency as a signal, and the humans read a three-week gap as "this company might not exist any more".

Pick two, sustain the rest#

The version that works is unglamorous.

Choose two platforms to run properly. The two where your buyers actually are, not the two you find most interesting. Run those at benchmark.

Let everything else run at a floor. Once a week, or once a fortnight, at a level you would still hit during your worst month of the year. A quiet but regular presence keeps the account credible and costs almost nothing.

Set the floor at your bad week, not your good one. This is the whole trick. Plan the cadence you can hold when a client is on fire and someone is on leave, because that week is coming and it is the one that breaks the streak.

Frequency only helps while quality holds#

There is a real ceiling. Posting more works right up until the extra posts are worse than the ones you were already making, and then it reverses: people learn that your name in the feed is usually not worth stopping for, and that impression is expensive to undo.

Short-form video is the partial exception. On TikTok in particular, volume is genuinely part of discovery, because each upload is another sample the recommendation system can test against an audience. Even there, the volume has to clear a floor of watchability.

Everywhere else, two considered posts beat six thin ones.

Batching is what makes a cadence survivable#

The reason a cadence collapses is rarely the writing. It is the context switching: opening four apps, remembering four formats, uploading four files, four times a week, in between everything else.

Batching kills most of that cost. One session, one subject, several posts, all scheduled forward. The work stops being a daily interruption and becomes a recurring appointment — and an appointment survives a busy week in a way that a daily obligation does not.

A practical shape that holds up:

• 90 minutes, once a week. One theme, one recording or writing session.
• Cut it into platform-native pieces. Not the same file five times; see the note on cross-posting.
• Schedule the whole week forward, into your tested time window.
• Leave one slot empty for whatever actually happens that week.

That last one matters more than it looks. A calendar with no room for a reactive post is a calendar you will break the first interesting week you have.

The number to actually pick#

Take your two priority platforms. Take the low end of the benchmark. Halve it if you are a team of one.

Then hold that for three months without missing. If it turns out to be easy, raise it. That is the only reliable way to find your real cadence, and it is considerably more useful than any table, including the one above.
