FAQ
About the tools.
Are these tools really free?
Yes. There is no sign-up, no trial and no watermark. They run in your browser, so they cost us nothing to run and we keep them free.
Do you store what I enter?
No. Calculations happen on your device. Images in the safe zone checker never leave your browser. The only thing we receive is a result summary if you choose to email it to yourself.
Which currencies do the calculators support?
Pounds, Pakistani rupees, US dollars, UAE dirhams, Canadian dollars and euros. Rates come from a free exchange-rate feed and update daily, with a fallback table if the feed is down.
Can I share a result with a colleague or client?
Yes. Every calculator has a "Copy link to this result" button. The link contains your inputs, so whoever opens it sees the same numbers.
How often are the ad specs updated?
We check them every quarter against each platform's own help pages, and every figure shows the date it was last checked and links to its source.
Can I embed a calculator on my own site?
Not yet. If that would be useful, tell us at hello@digitalgenixsolutions.com and we will prioritise it.
Who built these?
The founders of Digital Genix Solutions, a Manchester paid ads agency. They are the same calculations we use on client accounts.
Free · limited spots each week
Prefer a human to look at your account?
The tools give you the numbers. A free audit gives you a founder going through your actual campaigns and the three fixes that would make the biggest difference.
