Beyond the numbers
Friends is mostly American English. Accent and speed matter as much as vocabulary: if you know the words but can’t catch them, turn on English subtitles and slow down.

Watching plan
In TeakReader you can import the subtitles of any episode, see the words you don’t know yet, and study them as flashcards before you press play. How it works

We took English subtitles for 12 episodes spread across the first seasons (S1E1, S1E7, S1E13, S1E19, S2E1, S2E7, S2E13, S2E19, S3E1, S3E7, S3E13, S3E19), removed sound descriptions, speaker labels, and character names, and matched each of the 25,378 spoken words to the same frequency list we use for classic book levels. Speaking speed is spoken words divided by the time the subtitles are on screen. Only statistics and single words are shown here.
The recommended level is our estimate from vocabulary, speed, and style, not an official CEFR rating. Later seasons can be easier or harder.
FAQ
Friends is the easiest show we measured: under 2,900 different words across 12 episodes, and a B1 learner knows about 97% of what is said. A strong A2 learner can follow it with subtitles; at B1 it becomes comfortable. We recommend it from strong A2 to B1.
About 143 words per minute of dialogue, which is average for TV. Everyday conversation is often around 150 words per minute.
A learner who knows the most common 20,000 English word forms (our B1 band) knows about 96.9% of the words spoken. Research on listening suggests that knowing about 95% of the words is enough to follow most of what is said, so subtitles help until you reach that point.
