French Numbers 1–100: How to Count (And Survive 70, 80, 90)

French numbers from 1 to 69 work much like English — learn 1–16, then build the tens. Then, at 70, French famously goes rogue: 70 is soixante-dix (“sixty-ten”), 80 is quatre-vingts (“four-twenties”), and 90 is quatre-vingt-dix (“four-twenties-ten”), so 99 comes out as quatre-vingt-dix-neuf — literally “four-twenty-ten-nine.”

Yes, really. And yes, every learner has stood frozen at a market stall doing that arithmetic while the vendor waits. The good news: the system is completely regular once you see the logic, and this guide walks you from un to cent with pronunciation for every step.

Numbers 1–16: the ones you simply memorize

These sixteen are the foundation — everything above them is assembled from these parts.

#	French	Pronunciation	#	French	Pronunciation
1	un	uh(n)	9	neuf	NUHF
2	deux	DUH	10	dix	DEES
3	trois	TRWAH	11	onze	OH(N)Z
4	quatre	KAH-truh	12	douze	DOOZ
5	cinq	SAH(N)K	13	treize	TREHZ
6	six	SEES	14	quatorze	kah-TORZ
7	sept	SEHT	15	quinze	KAH(N)Z
8	huit	WEET	16	seize	SEHZ

A pronunciation quirk worth knowing early: six, huit, and dix change their sound depending on what follows. Alone or at the end of a phrase, the final consonant is pronounced (j’en ai six — “SEES”). Before a noun starting with a consonant, it goes silent: six croissants = “see krwah-SAH(N).” Before a vowel, it liaises: six ans = “see-ZAH(N).” The nasal “(n)” respellings mean the vowel goes through your nose and the n itself is never pronounced — the full mechanics are in my guide to French pronunciation.

17–69: the regular zone

From 17, French starts compounding, and it stays pleasantly logical until 69.

17–19 are “ten-seven,” “ten-eight,” “ten-nine”:

• 17 dix-sept (dee-SEHT), 18 dix-huit (deez-WEET), 19 dix-neuf (deez-NUHF)

The tens:

#	French	Pronunciation
20	vingt	VAH(N)
30	trente	TRAH(N)T
40	quarante	kah-RAH(N)T
50	cinquante	sah(n)-KAH(N)T
60	soixante	swah-SAH(N)T

Combining works like English, with two rules:

1. 21, 31, 41, 51, 61 insert “et” (and): vingt et un (vah(n) tay UH(N)), trente et un, soixante et un. No hyphen-and-no-et for anything else.
2. Everything else just hyphenates: 22 vingt-deux (vah(n)t-DUH), 35 trente-cinq (trah(n)t-SAH(N)K), 47 quarante-sept, 58 cinquante-huit, 69 soixante-neuf.

Note that vingt alone is “VAH(N)” — the gt is fully silent — but in 22–29 the t wakes up: vingt-trois = “vah(n)t-TRWAH.”

So far, so sensible. Now take a breath.

70–99: welcome to French math

Here’s the system that launched a thousand memes. Instead of inventing words for 70, 80, and 90, standard French builds them from arithmetic:

#	French	Literally	Pronunciation
70	soixante-dix	sixty-ten	swah-sah(n)t-DEES
71	soixante et onze	sixty and eleven	swah-sah(n) tay OH(N)Z
75	soixante-quinze	sixty-fifteen	swah-sah(n)t-KAH(N)Z
80	quatre-vingts	four-twenties	kah-truh-VAH(N)
81	quatre-vingt-un	four-twenty-one	kah-truh-vah(n)-UH(N)
85	quatre-vingt-cinq	four-twenty-five	kah-truh-vah(n)-SAH(N)K
90	quatre-vingt-dix	four-twenties-ten	kah-truh-vah(n)-DEES
91	quatre-vingt-onze	four-twenty-eleven	kah-truh-vah(n)-OH(N)Z
95	quatre-vingt-quinze	four-twenty-fifteen	kah-truh-vah(n)-KAH(N)Z
99	quatre-vingt-dix-neuf	four-twenty-ten-nine	kah-truh-vah(n)-deez-NUHF

The trick that makes it click: 70–79 recycles the teens on top of sixty (70 = 60+10, 71 = 60+11, 75 = 60+15… up to 79 = 60+19 soixante-dix-neuf), and 90–99 recycles the teens on top of eighty (91 = 80+11, 95 = 80+15). Once your brain accepts “the seventies and nineties are teen-numbers stacked on a base,” the whole block becomes two patterns instead of thirty words.

Three details for correctness:

• 71 takes “et” (soixante et onze) but 81 and 91 don’t (quatre-vingt-un, quatre-vingt-onze). French giveth logic, French taketh away.
• Quatre-vingts has an -s only when nothing follows: quatre-vingts (80) but quatre-vingt-trois (83). Purely a spelling matter — you can’t hear it.
• Why does this system exist? It’s a leftover from an old base-20 counting system (likely Celtic in origin) that medieval French used widely — Paris still has the Hôpital des Quinze-Vingts, the “Fifteen-Twenties” hospital, named for its 300 beds.

Teacher’s tip: Belgium and Switzerland quietly fixed this — septante (70), nonante (90), and in much of Switzerland huitante (80). Every French person understands these words, but in France using them marks you as Belgian or Swiss. For Parisian French, do the math like the locals.

100 and beyond, briefly

100 is cent (SAH(N)), and life becomes easy again: 101 cent un, 150 cent cinquante, 200 deux cents, 1000 mille (MEEL). The 70/80/90 logic carries into big numbers — 1999 was famously mille neuf cent quatre-vingt-dix-neuf, a small poem of arithmetic.

Where numbers ambush you in real life

Knowing the list is one thing; catching numbers at native speed is another. These are the four situations to train for:

• Prices. Ça fait dix-neuf quatre-vingt-quinze — “that’s 19.95.” French drops the word “euros” mid-price, exactly as English drops “dollars.” The killer combo is prices in the 70–99 range: 95 € = quatre-vingt-quinze euros.
• Phone numbers. French phone numbers are read in pairs: 06 12 84 71 93 comes out as zéro six, douze, quatre-vingt-quatre, soixante et onze, quatre-vingt-treize. Every pair from 70–99 forces the arithmetic — this is the final boss of French numbers, and it’s worth drilling on its own.
• Times and dates. Le train part à dix-huit heures quarante-cinq — the train leaves at 18:45. France uses the 24-hour clock in all official contexts, so hours run to vingt-trois (23).
• Ages and years. J’ai vingt-huit ans (“I’m 28” — with avoir, never être), en deux mille vingt-six (in 2026).

Once you can produce a price and understand a phone number, you’re functionally numerate in French — which pairs nicely with the café and shopping lines in my list of the 100 most common French phrases.

How to practice (so 90 stops requiring a pause)

• Drill the two hard blocks separately. Spend a week just on 70–79 and 90–99. Count aloud: soixante-dix, soixante et onze, soixante-douze… until the stacking feels mechanical, not mathematical.
• Read numbers around you in French. License plates, prices, page numbers, your phone’s clock. Ten micro-reps a day beat one long session.
• Practice hearing, not just saying. Have someone (or an app, or a French YouTube video) fire random prices at you and write down the digits. Production and recognition are separate skills — most learners can say quatre-vingt-quinze long before they can catch it at speed.
• Say your own phone number in French until it’s automatic. It’s the number sequence you’ll produce most often in real life, and it forces the pair-reading habit.

Numbers are also a perfect early milestone: they’re a closed system you can fully master in a couple of weeks, which does wonders for momentum — a theme I expand on in how long it takes to learn French.

FAQ

Why is 80 “quatre-vingts” in French?

It’s a fossil of a base-20 (vigesimal) counting system, probably inherited from Celtic languages, in which people counted in scores: one-twenty, two-twenties, four-twenties. Medieval French used many such forms — Paris’s Quinze-Vingts hospital (“fifteen-twenties” = 300) preserves one. Over the centuries, French standardized on base-10 words for most numbers but kept the old forms for 70, 80, and 90.

Do all French speakers say soixante-dix and quatre-vingt-dix?

No — Belgium and Switzerland use the simpler septante (70) and nonante (90), and much of Switzerland says huitante (80). All French speakers understand these variants, but in France they immediately mark you as Belgian or Swiss. If your target is the French of Paris, learn the soixante-dix / quatre-vingts / quatre-vingt-dix system — it’s what you’ll hear in every price and phone number there.

What’s the hardest part of French numbers for English speakers?

Not saying them — hearing them. Numbers 70–99 arrive as multi-word arithmetic at full native speed (quatre-vingt-quatorze = 94), and French phone numbers, read in pairs, are a relentless stream of exactly these. The fix is dedicated listening practice: have random prices and phone numbers read to you and transcribe the digits until decoding becomes instant.

When do six, huit, and dix change pronunciation?

Three cases. Alone or at the end of a sentence, pronounce the final consonant: j’en veux six (“SEES”). Before a consonant, drop it: six mois = “see MWAH.” Before a vowel, it liaises — s and x become a z sound: six ans = “see-ZAH(N),” dix heures = “dee-ZUHR.” The same three-way rule covers huit (WEET / wee / wee-t).

Is there an easy trick for 70–99?

Think of it as two patterns rather than thirty numbers. The seventies are “sixty + teens”: 72 = soixante-douze (60+12), 79 = soixante-dix-neuf (60+19). The nineties are “four-twenties + teens”: 92 = quatre-vingt-douze (80+12), 99 = quatre-vingt-dix-neuf (80+19). The eighties are just “four-twenties + units” like a normal decade. Two stacking rules, one memorized base — that’s the entire hard zone.
