Longer forms measure more finely, and some add facets under each trait.

Mini-IPIP
Donnellan, Oswald, Baird and Lucas's 20-item short form of the IPIP Big-Five Factor Markers
Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Intellect/Imagination. 5 domains, answered on a 5-point accuracy scale.
Items selected by Donnellan, Oswald, Baird and Lucas (2006) from the International Personality Item Pool, public domain.

Time~3 min
Compared against 1,009,226 people 79 groups: everyone and 78 countries3 things to know first
- Four items per scale. Published alphas run .65 to .77. A single unusual answer moves a score much further than it would on a longer form, so read the result as a rough placement rather than a precise one.
- Reports Neuroticism. The fourth trait is scored as Neuroticism here. The Big-Five Factor Markers score the same items as Emotional Stability, which runs the opposite way.
- Compared by country only. The reference data records no age or sex. The one demographic it has is a country, and that was read from each respondent's IP address rather than asked — so it says where they were browsing, not where they are from. A country comparison is rougher than the sex and age ones the IPIP-NEO forms offer.

MFQ-2
Atari, Haidt, Graham and colleagues' Moral Foundations Questionnaire-2
Care, Equality, Proportionality, Loyalty, Authority, and Purity. 6 foundations, answered on a 5-point describes-me scale.

Compared against 5,312 people 549 groups: everyone, 2 sexes, 7 age bands, 22 countries, 2 studies, and the 515 combinations6 things to know first
- Moral values, not personality. This measures how much weight you give six kinds of moral concern. It is not a personality inventory, and its scales are not comparable with any trait on the other forms.
- Six items per foundation. The paper reports reliabilities (omega) averaging .82 to .90 across 19 countries, which is good for six items but still short: one unusual answer moves a score further than it would on the long forms, so read it as a rough placement.
- Scored as sums. Each foundation is the sum of its six answers, from 6 to 30. The paper reports averages from 1 to 5 instead: divide by six to compare with it.
- No reverse-keyed items. Every statement is worded in the same direction, so someone who agrees with everything scores high on all six. Differences between your foundations say more than any one score on its own.
- Compared across 22 countries, in two samples. The reference data is the two samples the paper that introduced the MFQ-2 collected, recruited differently, and you can compare against either or both. Its national samples are about 205 adults from each of 19 countries, recruited by survey panels to match each country on age and sex; the paper built and tested the questionnaire on them. Its online panel is 1,410 adults who signed up to take paid surveys, matched to nothing: 1,157 in the United States, 175 in India and 78 in Canada; the paper used it to check what the scores go with. Country here is where respondents said they live, not an IP address. "Both samples" is everyone, so it leans American. Neither is a sample of the world: no country in Asia other than Japan and India is in either. Every combination of country, sex and age is offered, however small, and each shows how many people it holds: comparing yourself with 13 Japanese men in their thirties is possible, and it is up to you how much to read into it.
- Political content. Several items ask about country, authority, tradition and sexual behaviour. These are the scales that differ most between liberals and conservatives, which is much of why the questionnaire exists.

IPIP Big-Five Factor Markers
Goldberg's 50-item Big-Five Factor Markers from the International Personality Item Pool
Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Intellect. 5 domains, answered on a 5-point accuracy scale.
Goldberg's Big-Five Factor Markers, from the International Personality Item Pool (Goldberg, 1999), public domain.
Items50
Time~7 min
Compared against 1,009,184 people 79 groups: everyone and 78 countries5 things to know first
- Five broad traits, no facets. This form has no sub-scales. It tells you where you sit on five traits and nothing about the narrower components underneath them.
- Reports Emotional Stability. The fourth trait runs opposite to Neuroticism: a high score means calm. Do not compare it directly with a Neuroticism score from another inventory.
- “Intellect” is narrower than Openness. It covers ideas, vocabulary and imagination, but not the aesthetic and values components that longer inventories include under Openness.
- Lopsided keying. Emotional Stability has 2 positively-keyed items and 8 negatively-keyed ones, so someone who agrees with every statement scores near the floor on it.
- Compared by country only. The reference data records no age or sex. The one demographic it has is a country, and that was read from each respondent's IP address rather than asked — so it says where they were browsing, not where they are from. A country comparison is rougher than the sex and age ones the IPIP-NEO forms offer.

IPIP-NEO-120
Johnson's 120-item short form of the IPIP representation of the NEO-PI-R
Neuroticism, Extraversion, Openness To Experience, Agreeableness, and Conscientiousness. 5 domains + 30 facets, answered on a 5-point accuracy scale.
Items selected by Johnson (2014) from the International Personality Item Pool (Goldberg, 1999), public domain.

Compared against 619,150 people 27 groups: everyone, 2 sexes, 8 age bands, and the 16 combinations2 things to know first
- A short form of the 300. The best four items of each facet. Facet scores move around more than the long form's, though domain scores are close.
- Modesty reads one way only. All four Modesty items are reverse-keyed on this form, so a respondent who agrees with everything scores the floor on it. The 300 balances the same facet.

IPIP-HEXACO-240
Ashton, Lee and Goldberg's public-domain IPIP measure of the HEXACO model
Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience. 6 domains + 24 facets, answered on a 7-point agreement scale.
Items by Ashton, Lee and Goldberg (2007), from the International Personality Item Pool, public domain.

Time~30 min
Compared against 22,786 people 5 groups: everyone and 4 countries6 things to know first
- Six factors, not five. Adds Honesty-Humility, which the five-factor model has no scale for. It predicts exploitative behaviour that the Big Five largely misses.
- Answered on seven points. A raw total here is not comparable with a raw total from any five-point form on this site. Percentiles are.
- Emotionality is not Neuroticism. It includes sentimentality and excludes anger, which this model places under low Agreeableness instead.
- Agreeableness is split. The unwillingness to exploit others moves to Honesty-Humility, leaving tolerance of others' behaviour here.
- Smallest reference sample. 22,786 respondents, against hundreds of thousands for the other forms. It records no age or sex, and is thin enough that only four countries have enough respondents to compare against at all — and that country was read from each respondent's IP address rather than asked, so it says where they were browsing, not where they are from.
- Instructions are adapted. IPIP publishes no administration wording for these scales, so the instruction shown is partly this service's own.

IPIP-NEO-300
International Personality Item Pool representation of the NEO-PI-R (300 items)
Neuroticism, Extraversion, Openness To Experience, Agreeableness, and Conscientiousness. 5 domains + 30 facets, answered on a 5-point accuracy scale.

Compared against 307,313 people 27 groups: everyone, 2 sexes, 8 age bands, and the 16 combinations1 thing to know first
- The longest form here. Ten items per facet. Its facet scores are the steadiest of any inventory on this site, at the cost of about half an hour.
