Classe vs. lezione
While both Italian words classe and lezione can sometimes be translated as "class" in English, they refer to different concepts. Understanding their distinction is key to speaking Italian more accurately. Classe typically refers to the group of people or the physical place, whereas lezione refers to the instructional event or its content.
Classe
A1This word primarily refers to a group of students who study together, or the physical classroom where they meet. By extension, it can also mean social class or style, just like in English.
La mia classe è molto unita e studiamo spesso insieme.
(My class is very close-knit and we often study together.)

(The teacher asked the entire class to be quiet.)

(See you in the classroom in five minutes.)

(The university has lecture halls and not classrooms.)
È un abito di gran classe.
(It is a very classy dress.)
Il film analizza le differenze tra le classi sociali.
(The movie analyzes the differences between social classes.)
Lezione
A1This word refers to the lesson itself — the block of time dedicated to teaching and learning a specific subject. It can also mean the content of that lesson or a private class, like for music or sports. Figuratively, it can mean a "life lesson".
La lezione di storia di oggi è stata affascinante.
(Today's history lesson was fascinating.)

Summary
In short, classe is about the *who* (the group of students) and the *where* (the classroom). In contrast, lezione is about the *what* and the *when* (the teaching session and its content). A simple way to remember is: You attend a lezione (a lesson) inside a classe (a classroom) together with your classe (your class of fellow students).
