Type a sentence and this checks whether it is a pangram - a phrase that contains every letter of the alphabet at least once. 'The quick brown fox jumps over the lazy dog' sails through; 'Pack my box with five dozen liquor jugs' does too; your first attempt probably will not, and the missing letters are listed right under the verdict.
Bottom line: the check is set arithmetic, not an opinion. The sentence is reduced to its distinct lowercase letters, compared against the 26-letter alphabet, and whatever is absent is printed as the to-do list. A perfect pangram - all 26 letters exactly once, no repeats - gets flagged separately, because those are rarer by orders of magnitude: the classic brown-fox sentence uses 35 letters, three times the minimum.
The honest part: pangrams exist for a practical reason. Typesetters used them to display every glyph in a font, keyboard drills used them to touch every key, and type designers still use them to proof a face - which is why the same few sentences appear in every font preview you have ever seen. Writing a new one is a puzzle of coverage: every letter is a constraint, and the checker tells you exactly which constraints your draft still violates.
How to use
- Type or paste a sentence - capitals and punctuation are handled automatically.
- Read the verdict: pangram or not, with the count of distinct letters and the exact missing letters listed.
- Draft iteratively: fix the missing letters, watch the count climb to 26, and aim for a perfect pangram if you enjoy pain.
Frequently asked questions
What is a pangram?
A pangram is a sentence that uses every letter of the alphabet at least once. The canonical English example is 'The quick brown fox jumps over the lazy dog' - forty-two years of font specimens and typing drills have made it the most-read sentence most people never chose to read. A perfect pangram is the stricter species: all 26 letters with no repeats, which forces short, strange sentences that read like telegrams from a scrabble champion.
How does the pangram checker decide?
The sentence is normalized to lowercase letters only, then reduced to the set of distinct letters it contains - the same deduplication a set data structure exists for, which is the exact structure this check mirrors (the implementation reference is linked in the notes below the tool). Whatever the alphabet has that your set does not is the missing list. The counting is public on the page: distinct letters shown, missing letters shown, no black box.
What is the most famous pangram, and why that one?
'The quick brown fox jumps over the lazy dog' - and its dominance is an artifact of technology. It became the standard typing practice sentence because it touches every key, then the standard font specimen because it displays every glyph; Microsoft and Apple both shipped it in their type previews, so it is likely the most-reproduced original sentence in modern publishing. Older specimens favored the stranger 'Pack my box with five dozen liquor jugs' and 'How vexingly quick daft zebras jump' - both still pangrams, both still in the wild.
Are there perfect pangrams in English?
Yes, but they are brute-force rarities: 26 letters, no repeats, means the average letter gets one appearance and the sentence reads like a compressed headline. Known examples include 'Mr Jock, TV quiz PhD, bags few lynx' and 'Cwm fjord bank glyphs vext quiz' - the latter leans on Welsh borrowings (cwm, a valley) that purists accept and pedants dispute. The checker flags any 26-distinct-letter sentence as perfect automatically, whatever vocabulary you had to raid to get there.
