The Tricky Teens: 11 to 19

16: Dieciséis
17: Diecisiete

21: Veintiuno
22: Veintidós
25: Veinticinco
29: Veintinueve
Counting from 30 to 99
From 30 onward, the spelling becomes incredibly straightforward. You write the tens column, add the word y (and), and then add the single digit.

Going Big: Numbers in Spanish 100 to 1000
Moving beyond one hundred might seem intimidating, but it follows the exact same logical structure you have already learned. When dealing with numbers in spanish 100 to 1000, you simply stack the hundreds block on top of the tens and units.
The Rule for 100
The number 100 on its own is cien. However, if there is any number following it, cien changes to ciento.
100: Cien
101: Ciento uno
154: Ciento cincuenta y cuatro
Scaling Up: Spanish Numbers by 100
To count efficiently up to a thousand, you need to recognize the plural forms of the hundreds. Review this list of spanish numbers by 100 to spot the patterns:
100: Cien / Ciento
200: Doscientos
300: Trescientos
400: Cuatrocientos
500: Quinientos (Irregular)
600: Seiscientos
700: Setecientos (Irregular)
800: Ochocientos
900: Novecientos (Irregular)
1,000: Mil
Grammar Note: Hundreds must agree in gender with the noun they describe. If you are talking about 200 houses (casas, feminine), you must say doscientas casas.
Perfecting Your Writing: Spanish Numbers Spelling
Paying attention to spanish numbers spelling is vital if you want to write checks, fill out official documentation, or pass a language certification exam.
Key Accents to Remember
As you learn the spelling rules, keep an eye out for written accents. These are crucial for correct pronunciation:
Dieciséis (16)
Veintidós (22)
Veintitrés (23)
Veintiséis (26)
One Word vs. Three Words
Remember that numbers 1 through 29 are written as a single word (e.g., veinticuatro). Numbers 31 through 99 are written as three separate words (e.g., treinta y cuatro).
Ordering Things: Spanish Numbers Ordinal
We use ordinal numbers to talk about sequences, floors of a building, or centuries. Mastering spanish numbers ordinal forms will add an extra layer of fluency to your speech.
Unlike cardinal numbers, ordinals always match the gender and number of the noun they modify.
1st: Primero / Primera
2nd: Segundo / Segunda
3rd: Tercero / Tercera
4th: Cuarto / Cuarta
5th: Quinto / Quinta
6th: Sexto / Sexta
7th: Séptimo / Séptima
8th: Octavo / Octava
9th: Noveno / Novena
10th: Décimo / Décima
Example: Vivo en el cuarto piso. (I live on the fourth floor.)

Frequently Asked Questions (FAQ)
What is the rule for the number 100 in Spanish?
The number 100 is written as cien when it stands alone or directly modifies a noun (e.g., cien dólares). It changes to ciento when followed by another number (e.g., ciento cinco).
Do Spanish numbers change based on gender?
Yes, certain numbers change. The number uno becomes un before masculine nouns and una before feminine nouns. Hundreds (from 200 to 900) also change endings to match the noun gender (e.g., doscientos hombres vs. doscientas mujeres).
Is there a comma or a period used for thousands in Spanish?
Traditionally, many Spanish-speaking countries use a period or a space to separate thousands, and a comma for decimals (e.g., 1.000 or 1 000 means one thousand). However, due to global digital standards, usage varies by region.
