Mandarin vs Cantonese: what's actually different
Mandarin and Cantonese are both "Chinese", and a speaker of one cannot understand a speaker of the other. They share most of a writing system, a long history and a great deal of vocabulary at the level of the character — and differ in sound, grammar words, everyday vocabulary, script and status. This is the head-to-head; each difference links to a page that goes into it properly.

Can they understand each other?
No. Chinese is a family of varieties, and the major groups are, in the words of Wikipedia's survey of them, "often mutually unintelligible, differing at least as much as different Romance languages". Mandarin and Cantonese are two of those groups: the relationship is closer to Spanish and French than to American and British English. What makes Chinese unusual is that both can be written with the same characters, so formal writing is readable across the divide, while neither can follow the other's speech. The wider question of what these varieties are — languages or dialects — is on what is a Chinese topolect.
Who speaks which
Mandarin is by far the larger: 990 million first-language speakers, and far more as a second language, because Standard Chinese — based on Mandarin — is the language of school and government throughout mainland China. The Yue group, which includes Cantonese, has about 85 million speakers.
Hong Kong is where Cantonese is strongest. Its 2021 census found 90.6% of residents speaking Cantonese as their usual language (down from 91.5% in 2011), while the share able to speak Putonghua rose from 49.5% to 56.5% — bilingualism, not replacement. How every branch of Chinese compares in size is on the Chinese languages, by number of speakers, and whether any of them is dying is on are Chinese topolects dying.
Tones
Cantonese has more of them: 6 tones by the usual modern count, or 9 if the syllables ending in -p, -t and -k are counted separately, as the traditional phrase 九声六调 ("nine sounds, six tones") does. Mandarin has 4 and a neutral tone. More tones means more distinctions to hear and produce, and Wikipedia notes the difficulty this poses for Mandarin speakers learning spoken Cantonese as adults. Which Chinese language has the most, and why the counts disagree, is on which Chinese language has the most tones.
Sounds
Cantonese kept the syllable endings of Middle Chinese — -m, -p, -t, -k as well as -n and -ng — and Mandarin lost most of them. That is why the same character can sound so different: 十, "ten", is shí in Mandarin and sap in Cantonese.
Writing
Formal writing in both is standard written Chinese, which follows Mandarin grammar and vocabulary. The difference is that Cantonese also has a written form of its own, with characters for words Mandarin does not use — 係 (is), 唔 (not), 冇 (have not), 嘅 (the possessive particle) — used in Hong Kong advertising, magazines, social media and quoted speech. Few other Chinese languages have that; why is on why most Chinese topolects have no written standard.
Script is the other visible difference. Hong Kong and Macau use traditional characters; mainland China uses simplified ones. That is a matter of place, not of language — Mandarin in Taiwan is written in traditional characters too.
Which should you learn?
- Mandarin if you want the most speakers, mainland China and Taiwan, the national standard, and the most teaching material. It is also, with Cantonese, one of the only two Chinese varieties commonly taught at university outside China and Taiwan.
- Cantonese if you want Hong Kong, Guangdong or a Cantonese-speaking family, and a film and music culture of its own. It takes more tones and a second set of written words.
Mandarin is one of the harder languages for English speakers, mostly because of tones and characters rather than grammar — the details are in is Mandarin hard to learn. If you are weighing Cantonese against another southern variety, Shanghainese vs Cantonese compares the two.
The most common Mandarin words are free, with pinyin, and the Mandarin course starts from the first of them.
