# Audience size limits

The maximum and minimum audience sizes Primer enforces, and how to split an audience that's too large.

## Maximum size

A regular audience is capped at **3,000,000 records**. If your filters estimate more than that, Primer cuts the audience off at the maximum and shows a message on the estimate.

[Exclusion audiences](/primer/primer-support-review/audiences/exclusion-audiences.md) have a much higher cap of **50,000,000 records**, because they're used to remove people from targeting rather than to target them.

## Minimum size per destination

Each ad destination needs a minimum estimated audience size before you can sync to it. If your audience is below the minimum, Primer shows: *"Recommended audience size for {destination} is >{n} records. Adjust your filters."*

| Destination | Minimum audience size |
| ----------- | --------------------- |
| Google      | 100                   |
| Meta        | 100                   |
| LinkedIn    | 300                   |
| Reddit      | 1,000                 |
| DV360       | 1,000                 |
| Microsoft   | 300                   |

Matching drops records the platform can't identify, so the delivered audience is smaller than your estimate. A few destinations also enforce a minimum on the **matched** count — Meta needs at least 1,500 matched records to deliver. Aim comfortably above the minimum so you clear it after matching. See [Match rates](/primer/primer-support-review/audiences/match-rates.md) for how much shrinkage to expect.

## Active audience slots

Separate from how *big* an audience can be, your plan limits how *many* audiences you can have active at once. An audience counts against this slot limit while it's in a working state — **Matching**, **Ready**, **Incomplete** or **Running**. Drafts and archived audiences don't count.

When you hit the limit, [archive](/primer/primer-support-review/audiences/duplicating-and-archiving.md) an audience you no longer need to free a slot, or purchase extra slots. Your slot count comes from your subscription, so it varies by plan — see [Plans and trials](/primer/primer-support-review/billing-and-plans/plans-and-trials.md).

## Splitting an audience that's too large

If an audience estimates above the 3M cap, split it into several audiences that each fall under the cap, using filters that don't overlap — for example by geography, company size, or industry — so no record lands in two audiences. Build and sync each one separately.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.sayprimer.com/primer/primer-support-review/audiences/audience-size-limits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
