Find The Norm
Ask whether something about you is normal and what comes back is almost always opinion. A friend's hunch, a forum reply from years ago, a magazine headline that has not been near a study in two decades. The measured answer usually exists, sitting in a government survey or a journal article, and it very rarely reaches the person who wanted it.
This site closes that gap in one step. You put your number in, the calculator places it on the distribution the research actually drew, and the study it came from is named on the same page instead of buried somewhere in a footer.
Coverage runs across physical dimensions, health, psychology, intimacy, finance, relationships, education, fitness and lifestyle, which comes to over 320 calculators in 14 categories. Every one of them stands on a named source, whether a peer-reviewed study, a government survey, a clinical dataset or a published poll. Nothing here is a guess with a decimal point added.
Why this exists
Almost every question about whether you are normal already has a measured answer sitting in a study somewhere. The only job here is to hand it over with the source still attached.
There is an odd hole in what gets published about ordinary bodies and ordinary lives. Clinical thresholds are defined precisely, because doctors need a line to work from, and the extremes get written about because they make better copy. The middle of the distribution, where nearly everybody actually lives, goes unnamed. So people search for it and find a thread of strangers guessing at each other.
A percentile fixes that, because it neither pathologises nor flatters. It puts you on a curve somebody has already drawn from real measurements, answering the question you were going to ask anyway. Whether the answer turns out to be reassuring is the data's business, and we don't soften it in either direction.
The data principle
Every figure traceable
Each calculator stands on one specific peer-reviewed study, government dataset or institutional survey. The study, its authors, the sample size and the year of publication all sit in the citation strip on the calculator page, so you can check the work without leaving. Nothing gets invented, and nothing gets lifted from a secondary source that read the original on our behalf.
A figure that cannot be traced back to a primary source does not get a calculator, however good the search volume looks. Several planned pages have died on that rule.

The person behind it
James Maclean builds this, a Creative Director working in London. Every calculator, every citation and every line of copy comes from one person who got tired of watching that question answered with a shrug. Spot a figure that looks wrong, or a study that has quietly been superseded, and [email protected] reaches him directly. He reads all of it.
Where to go next
The methodology page carries the technical detail, including how a percentile gets built when a source only publishes a mean and a standard deviation. Journalists will find boilerplate, headline stats and citable calculators on the press page.
