How to Calculate Indoor-Screen Reach in Kyiv 2026

"And how many people will see this?" is the first question any advertiser asks. In outdoor advertising it's often answered with pretty but opaque figures — "potential reach" in the hundreds of thousands. For an indoor screen in a coffee shop, there's a more honest and simpler way to calculate real reach — based on the venue's number of visitors. Let's break down the method without the fog.

Why "millions of impressions" isn't reach

The big problem with industry figures is a sleight of hand with terms:

• Impressions (OTS) — how many times the ad could theoretically have been seen
• Reach — how many unique people saw it
• Frequency — how many times on average one person saw it

A billboard "audience of 300,000" is mostly impressions flashing past a car window at speed. An indoor screen works differently: a smaller volume, but a quality, repeated contact with a person sitting at a table. According to data from the industry association VRK, digital out-of-home advertising (DOOH) is the most dynamic media segment precisely because it delivers a measurable contact rather than an abstract "flow."

The basic indoor-screen reach formula

The starting point is the venue's traffic — that is, the number of visitors (receipts) per day:

Monthly visits = visitors/day × working days per month
Reach (unique) ≈ monthly visits × share of new visitors
Contacts (impressions) ≈ monthly visits × ad repeats per visit

Example for a coffee shop with ~150 receipts/day:

• Visits per month: 150 × 30 ≈ 4,500
• Repeats per visit: a person sits 15–30 min, the spot is 15 sec on a loop → 5–10 impressions
• Contacts per month: 4,500 × 5–10 ≈ 22,500–45,000 impressions
• Unique reach: depends on the share of regular guests; a craft coffee shop has lots of "regulars," so unique reach is lower but frequency is higher — and that's good for recall

Note: high frequency on a loyal audience is an advantage, not a drawback. The brand is seen not once but systematically. Why this works is in the article 7 metrics for outdoor advertising effectiveness.

Reach vs frequency: which do you need

Depending on your goal, you optimize different indicators:

• You need reach (new product, grand opening) → more venues, fewer months
• You need frequency (cement the brand, a promo) → fewer venues, but longer and regular

One venue for 3 months and three venues for 1 month deliver similar total impressions, but a different balance of reach/frequency. For a test, people usually take 2–3 venues per month.

How to translate reach into money: cost per contact

To compare indoor with other channels, calculate CPM (cost per 1,000 contacts):

CPM = (monthly screen price / contacts per month) × 1000

If a screen costs a transparent monthly owner's price and delivers tens of thousands of quality contacts, the CPM often comes out competitive with digital — without the 15–30% agency markup that inflates that CPM.

Why HostAd shows reach honestly

HostAd calculates reach not "out of thin air," but from the venue's real traffic:

• Transparent data for each screen — you see a reach estimate for a specific coffee shop before booking, right on the map
• Owner's price with no markup — CPM is calculated from the surface's real price, not from an inflated agency rate
• Monthly booking — you can start with one venue, measure actual QR traffic, and scale based on data
• A map instead of phone calls — you compare the reach and price of nearby venues on /map, with no sales proposals

This way the estimate stops being "marketing magic" and becomes an ordinary calculation: traffic × repeats × price.

Summary

Indoor-screen reach is calculated honestly and simply — from the venue's number of visitors, not from abstract "millions past a window." The smaller volume is offset by quality, repeated contact with a loyal audience, and the transparent owner's price makes CPM predictable.

What to do today:

1. Go to the HostAd map and look at the reach estimate for venues in your district
2. Estimate the contacts: visits × ad repeats per visit
3. Calculate CPM from the transparent owner's price and compare it with your current channel
4. Launch one venue for a month and check the calculation against actual QR traffic
