Pro*por"tion, n. Etym: [F., fr. L. proportio; pro before + portio
part or share. See Portion.]
1. The relation or adaptation of one portion to another, or to the
whole, as respect magnitude, quantity, or degree; comparative
relation; ratio; as, the proportion of the parts of a building, or of
the body.
The image of Christ, made after his own proportion. Ridley.
Formed in the best proportions of her sex. Sir W. Scott.
Documents are authentic and facts are true precisely in proportion to
the support which they afford to his theory. Macaulay.
2. Harmonic relation between parts, or between different things of
the same kind; symmetrical arrangement or adjustment; symmetry; as,
to be out of proportion. "Let us prophesy according to the proportion
of faith." Rom. xii. 6.
3. The portion one receives when a whole is distributed by a rule or
principle; equal or proper share; lot.
Let the women . . . do the same things in their proportions and
capacities. Jer. Taylor.
4. A part considered comparatively; a share.
5. (Math.)
(a) The equality or similarity of ratios, especially of geometrical
ratios; or a relation among quantities such that the quotient of the
first divided by the second is equal to that of the third divided by
the fourth; -- called also geometrical proportion, in distinction
from arithmetical proportion, or that in which the difference of the
first and second is equal to the difference of the third and fourth.
Note: Proportion in the mathematical sense differs from ratio. Ratio
is the relation of two quantities of the same kind, as the ratio of 5
to 10, or the ratio of 8 to 16. Proportion is the sameness or
likeness of two such relations. Thus, 5 to 10 as 8 to 16; that is, 5
bears the same relation to 10 as 8 does to 16. Hence, such numbers
are said to be in proportion. Proportion is expressed by symbols
thus: a:b::c:d, or a:b = c:d, or a/b = c/d.
(b) The rule of three, in arithmetic, in which the three given terms,
together with the one sought, are proportional. Continued proportion,
Inverse proportion, etc. See under Continued, Inverse, etc.
– Harmonical, or Musical, proportion, a relation of three or four
quantities, such that the first is to the last as the difference
between the first two is to the difference between the last two;
thus, 2, 3, 6, are in harmonical proportion; for 2 is to 6 as 1 to 3.
Thus, 24, 16, 12, 9, are harmonical, for 24:9::8:3.
– In proportion, according as; to the degree that. "In proportion
as they are metaphysically true, they are morally and politically
false." Burke.

another; as, to proportion the size of a building to its height; to
