This is measured b the number of syllables in each line.  A 5 foot syllable line is called a penemeter (Meaning 5) 

Note - The Official How To Rap Manual Touches on the different types of meters

Remember two units (or syllables) are considered a foot in poetry.  Each foot has certain stress patterns.  There are five different stress patterns that can associate with a foot, and not all of them are 2
syllables.  We'll touch on everything briefly in the paragraphs below.

STRESS PATTERNS

In all, there are only five possible stress patterns available.  These are

Iamb              Unstressed + Stressed              2 Syllables
Trochee        Stressed + Unstressed              2 Syllables
Spondee      Stressed + Stressed                 2 Syllables
Anapest        Unstressed + Unstressed + Stressed     3 Syllables
Dactyl    Stressed + Unstressed + Unstressed     3 Syllables

Like in poetry meter plays a big part in music.  So I think it would be
a great place to spend a little time on.  Poetry meter is another avenue
that I believe every rapper should strive to acknowledge.  With that
said lets talk about the different kinds of meter.

The length of lines in poetry can very just like the length of your
bars.

Below is a list of the different types of meter and line length.

Monometer         1 foot
Dimeter        2 foot
Trimeter               3 foot
Tetrameter          4 foot
Pentemeter         5 foot
Hexameter          6 foot
Heptameter        7 foot
Octameter           8 foot

Meter is determined by the type of foot and the number of feet in a line.  We'll leave you with an example.

For example - A line with 6 dactylic feet is known as dactylic hexameter.  A line with 3 iambic feet is known as iambic trimeter. 

That's all for now. 

Good luck

Poetry In Rap - Some Basics
As you already know, poetry plays a humongous part in rap music.  With that said we're going to talk briefly about stressed and unstressed syllables.  We get tons and tons of emails concerning questions, views and comments about stressed and unstressed syllables.

Another word for stressed in poetry is accented.  Stressed or accented syllables or the long part of the syllable and the unstressed or unaccented syllable is also called the short part of the syllable.  In verse as well as in poetry syllables are done in meter.

In poetry meter is a reoccurring pattern of stressed and unstressed syllables in a set pattern.  A pair of stressed and unstressed syllables are known as a foot.  So in poetry you could have a poem with 5 feet lines.

Remember I told you in poetry lines are measured in meter. 
"Poetry plays a big part in rap.  Some have said all rap is, is poetry with some music behind it.  Some of the greatest lyrcists of all time have been huge fans and students of poetry."
