The calculator below can check if a phrase is a pangram. If you wonder what a pangram is, here is a short extract from wikipedia:
A pangram (Greek: παν γράμμα, pan gramma, "every letter") or holoalphabetic sentence is a sentence using every letter of a given alphabet at least once. Pangrams have been used to display typefaces, test equipment, and train handwriting, calligraphy, and keyboarding skills.
The best known English pangram is "The quick brown fox jumps over the lazy dog." It has been used since at least the late 19th century and was utilized by Western Union to test Telex / TWX data communication equipment for accuracy and reliability. It is now used by several computer programs (most notably the font viewer built into Microsoft Windows) to display computer fonts.
Short pangrams in English are more difficult to come up with and tend to use uncommon words. A perfect pangram contains every letter of the alphabet only once and can be considered an anagram of the alphabet; it is the shortest possible pangram. An example is a phrase "Cwm fjord bank glyphs vext quiz" (cwm, a loan word from Welsh, means a steep-sided valley, particularly in Wales). Most such examples are not usually understood even by native English speakers, so arguably are not really English pangrams. Perhaps the most easily understood perfect pangram is "Mr. Jock, TV quiz Ph.D., bags few lynx"—but it includes three abbreviations (Mr, TV, and Ph.D.).
Here are some short pangrams using standard written English, not involving abbreviations or proper nouns:
"Pack my box with five dozen liquor jugs." (32 letters)
"Jackdaws love my big sphinx of quartz." (31 letters)
"The five boxing wizards jump quickly." (31 letters)
"How vexingly quick daft zebras jump!" (30 letters)
"Bright vixens jump; dozy fowl quack." (29 letters)
"Sphinx of black quartz, judge my vow." (29 letters)
Longer pangrams may afford more opportunity for humor, cleverness, or thoughtfulness.
