The length of a note is referred to as its "duration." Duration indicates how long a note is held or played in a piece of music, typically expressed in terms of rhythmic values such as whole notes, half notes, quarter notes, and so on. It is an essential aspect of musical notation that affects the overall rhythm and flow of the composition.
Generally it is 8x12 inches.

A century.
The diameter is 24.26 mm (0.955 inches) Note that a quarter is circular so it doesn't actually have a length, which describes linear distance.
a demisemiquaver is the length of half a semiquaver
A quaver is half the length of a crotchet. A semi quaver is a quarter of a crotchet's length . A minum is double its length while a dotted minum is three times it length. A semibreve is four times the length of a crotchet.

It is called duration.
The dot next to a note increases its length by half of its original length. For example, the dotted half note. The dot increases the half note's length by half of its original length (which is 2 quarter beats) so the dotted half note is worth 3 quarter beats. It also works on rests. This also applies to other instruments.
A call note is the note naturally used by a male bird in call to a female - sometimes also used by birdwatchers to try and trick birds into appearing.
To arrange the elastic in sequence from the highest note to the lowest note produced, you should stretch the elastic to varying lengths and pluck it. The shorter the length of the elastic, the higher the note it produces. Conversely, a longer stretch will yield a lower note. Thus, you would start with the shortest elastic length for the highest note and progress to the longest length for the lowest note.
The duration of a minim is as twice as it of a crotchet.
The sound of the half note depends on which note is being played. A half note represents length, not tone.
It is called duration.
The Americans call it the half note and the English call it a semi-breve.
They call it a Quaer.
