Determine your Bra pattern Size

Measuring for a bra should be done with your best-fitting bra on, but not a foam cup bra as this will not be accurate. If you don’t have a bra that fits, the measurement will not be totally accurate since the breast tissue will be compressed. Hold the tape measure level and not twisted.

BAND SIZE
To determine your size using the Pin-up Girls bra patterns, you need only two measurements. It doesn’t matter if you use inches or centimeters, just as long as you use the same for both measurements. Measure the high bust, pulling the tape snug against the skin but not tight.


The high bust measurement determines your band size. The chart below should help determine your band size.

If your High Bust Measures
Use this Band Size
29 - 31” (73.5 cm – 78.5 cm)
30
31 - 33” (78.5 cm -83.5 cm
32
33 - 35” (83.5 cm – 89)
34
35 - 37” (89 cm – 94 cm)
36
37 - 39” (94 cm – 99 cm)
38
39 - 41” (99 cm – 104 cm)
40
41 - 43” (104 cm – 109 cm)
42
43 - 45” (109 cm – 114.5 cm)
44
45 - 47” (114.5 cm – 119.5 cm)
46
47 - 49” (119.5 cm – 124.5 cm)
48


CUP SIZE
Now measure over the fullest part of the bust, but do not pull the tape snug, just tight enough to keep it from sliding down. This is the full bust measurement.


To determine the cup size, subtract the high bust from the full bust measurement. The difference determines the cup size

If the Difference is
Use this Cup Size
0 - 1/2” (0 - 12 mm)
AAA
1/2 – 3/4” (12 - 20 mm)
AA
3/4 – 1 3/4” (2 – 4.5 cm)
A
1 3/4 – 2 3/4” (4.5 cm – 7 cm)
B
2 3/4 – 3 3/4” (7 cm – 9.5 cm)
C
3 3/4 – 4 3/4” (9.5 cm – 12 cm)
D
4 3/4 – 5 3/4” (12 cm – 14.5 cm)
E
5 3/4 – 6 3/4” (14.5 cm – 17 cm)
F
6 3/4 – 7 3/4” (17 cm – 19.5 cm)
G
7 3/4 – 8 3/4” (19.5 cm – 22.5 cm)
H

If the chart size is greatly different from your ready-to-wear bra size, and that size fits you, make a trial bra in your ready-to-wear size and assess the fit. Getting the right fit in the cups is the most important thing. If the cups fit but the band doesn’t, the band is easy to adjust.

If the band fits but the cups are too small, go up one cup size
If the band fits but the cups are too large, go down one cup size

If the cups fit, but the band is too short – lengthen the band
If the cups fit, but the band is too long – shorten the band
