Banners get cropped differently on every platform and every screen. Designing without knowing where the crop lands is how the phone number ends up cut off.
A banner is rarely shown at the exact shape you designed it. Platforms crop for different screens, and your website's hero area is a different shape on a phone than on a laptop.
Design without accounting for that and the result is predictable: text cut in half, a logo half off the edge, a phone number invisible on mobile.
The practical technique is to treat the middle of the banner as the only reliable space. Anything essential — the message, the logo, the number — lives there. The edges carry background that can be cropped without loss.
This is why banners with edge-to-edge text almost always break somewhere.
Everything the business does, listed in one banner, at the same size. Nothing stands out, so nothing gets read — and on a phone it's too small to read anyway.
One message, big enough to read at a glance, wins. A banner is not a brochure.
Paid placements have their own rules on top of this, covered in ad creative for campaigns. Each platform has its own dimensions and its own crop behavior, and they change. Two things stay true regardless: keep the essential content centered, and design assuming it will be seen small on a phone.
Profile images are worth attention too — that's your logo at its smallest, which is exactly the test covered in custom logo concepts.
Banners made one at a time drift from your other materials. Using the same colors and type every time is what makes a customer recognize you across a site, a social page and a flyer — see full brand color palette and brand identity.
