Threads vs Instagram: Which Platform Delivers More Reach Per Hour? (Real Data Analysis)

For the past year, we've quietly tracked what happens to 162,000 posts after they go live. Our customers published them through Mirr on Threads, Instagram, and YouTube, and together they've earned more than half a billion impressions. The totals weren't what surprised us most. It was the gap between what a typical Threads post does in five minutes and what a typical Instagram post does in two hours.

Put simply: hour for hour, Threads delivers roughly 8 to 10 times more reach than Instagram for the same effort. We didn't expect to publish that conclusion. But the data kept saying it, no matter how we sliced it.

Key takeaways

• Across 162,000+ posts in our dataset, Threads' median post reaches 542 people; Instagram's median reaches 322.
• Even at the 25th percentile, a Threads post reaches 172 people. The 25th-percentile Instagram post reaches 39. That's a floor about 4x lower.
• A Threads post takes 3-10 minutes to make. An Instagram post takes 30 minutes to 2 hours.
• For solo operators with no design or video team, Threads is the obvious place to start. Instagram earns its keep when you're optimizing for purchase intent, not raw reach.

The trap of averages

If you only look at averages, Instagram looks dominant: 9,193 average views per post versus 3,552 for Threads. But the average is misleading. On Instagram, a few viral posts hit millions of views. They pull the average up, while most posts land far below it. The median, meaning the typical post in the middle, is what most accounts actually get. There, Threads beats Instagram 542 to 322.

The 25th percentile makes the gap sharper. A Threads post that "underperforms" in our dataset still finds 172 people. The same percentile on Instagram lands at 39. That's the difference between a slow day and a post no one saw.

Why the time math doesn't favor Instagram

Reach per post is only half the question. The other half is what it took to make that post. A Threads post is text. You write it and you publish it. An Instagram carousel needs a layout, a font choice, ten slides of copy, and an eye-catching cover image. A Reel needs a script, filming, editing, captions, and music. The extra work comes from the format itself, not from people being lazy.

You can see that extra work in our user data: the average Mirr account publishes 154 posts to Threads and 72 to Instagram. People aren't choosing to neglect Instagram. The format just takes more work.

Do the rough math. In an hour, you can make six to ten Threads posts at a median reach of 542, or one or two Instagram posts at a median reach of 322. That works out to somewhere between 3,200 and 5,400 reach per hour on Threads, and 320 to 640 per hour on Instagram. Whichever end of the range you take, the ratio is about 8-10x.

Engagement, not just reach

Reach without engagement is just a number that looks good. On engagement, Threads pulls even further ahead. Buffer's analysis of 10.2 million posts put Threads' median engagement rate at 6.25%, ahead of X at 3.6%. Socialinsider's 2025 Instagram benchmarks have Instagram's overall engagement rate sitting at 0.48%, with carousels still the leading format at 0.55%.

That's a gap of about an order of magnitude, and it's real. It's also a reason to be careful. Strong engagement on a Threads post with 500 views still means 500 views. On Instagram, a viral Reel with a lower engagement rate can still send a meaningful number of people to your store.

When Instagram earns its hours back

None of this means you should abandon Instagram. It means you should be honest about why you're there. Instagram still wins in three areas that matter. It's better for building a visual brand when the photo is the product. Its ad tools are mature and can target precisely. And its viral ceiling really is higher than Threads'.

If you sell something visual, like food, beauty, travel, or physical goods, a good Instagram presence pays for itself in a way Threads can't match yet. If you sell SaaS, services, or anything people decide to buy by reading, the extra hours are harder to justify.

What we'd actually do

If you're solo and starting from zero, put all your effort into Threads for a quarter. Two to three text-only posts a day is a pace you can keep up. Get better at writing, learn what your audience responds to, then add Instagram once you can see what works.

If you're a small team with some design capacity, our rough rule has been 70% Threads, 30% Instagram. Use Threads to test ideas — what gets saved, what gets replied to — then turn the winners into carousels and Reels. You stop guessing what to design.

If you have a full content team, run both platforms at the same time, but stop posting identical content to both. People read differently on each platform, so a post written for one usually feels a little off on the other. We built Mirr partly to make that adaptation step easier: one idea, two versions that each feel at home on their platform. But the principle holds whether you use a tool or not.

Frequently asked questions

Can a Threads account with zero followers still get reach?

Yes. Threads ranks posts mostly by what people are interested in, not just by who follows you. Even posts in the bottom quarter of our dataset still get 172 views. That doesn't guarantee growth, but the minimum is real.

Should I cross-post the same content to both?

We'd avoid copy-paste. Threads readers expect a certain rhythm — short, conversational, often a single idea per post. Instagram captions can carry more weight. Use Threads to find what people care about, then re-shape it for the slower, more visual surface.

Is Reels or carousels the better Instagram bet?

Reels reach more new people. Carousels get deeper engagement from people who already know you. If you're growing an audience, lead with Reels. If you're building on the audience you have, carousels do more work per post.

What time period does the Mirr data cover?

January 2025 through February 2026. Threads accounts have been publishing through Mirr for longer. Instagram integration launched in December 2025, so its data covers a shorter period. As more Instagram data comes in, the numbers may shift slightly.
