When opinions aren't enough.

A logo report saves you a fight, a bad print run, or an expensive misstep.

“Your client keeps pushing back on your design.”

Every revision round is an opinion war. A report turns the conversation from taste to data: contrast ratios, legibility tests, and balance maps they can't argue with.

Ship the report instead of arguing.

“You paid for a logo and you're not sure it's any good.”

Designers said it's great. Friends said it's great. But before you commit to merch, signage, and thousands of business cards, get a second opinion that isn't trying to be polite.

Test it before you print 5,000 business cards.

“You inherited a brand and don't know its weak spots.”

The logo predates you. It might be solid, it might not be, and your team has zero appetite for a redesign without proof. Run a report, find the gaps, and build a case.

Audit your logo against real design principles.

The questions every logo should be able to answer.

Each test answers a question you or your client is already asking.

Visual clarity

“Will it still read on a business card?”

See exactly what sizes your logo looks great at and where it starts to lose detail.

Contrast & accessibility

“Is it accessible to everyone?”

Background compatibility and live colorblindness simulations across every common variant.

Shape & balance

“Is it visually balanced?”

Optical weight, detail distribution, and whether complexity matches the intended size.

Layout flexibility

“Will it fit anywhere you need it?”

See how your logo fits into a wide variety of aspect ratios to find the best ways to utilize it in the wild.

Color harmony

“Do the colors actually work together?”

Palette compatibility, emotional read, and whether your color story matches your brand.

AI insights

“What does it say about your brand?”

Plain-language strengths, weaknesses, estimated audience, and brand personality.

Every report ships as a shareable link and a polished PDF. Send it to your team, hand it to a client, or drop it into a deck.

I run into stubborn clients sometimes and the reports are the perfect things to share with them to help me back up my design choices.

Not really a designer, but the reports are surprisingly thorough. Pretty easy to use it to test out my company's branding.

The AI insights are honestly great. Basically like having a random person on the street look at your design and tell you what they think. Handy.

We don't change our branding much, but this was a great test to make sure our current logo was on par and working for our customers!

Used the old version of logo lab for years but the updates are incredible! The sizing and color palette sections are my favorites.
