HOW TO DETERMINE YOUR RING SIZE
Ring sizing is tricky! We created this guide to help but we highly recommend going to a local jeweler and getting sized in person.
Many of our rings are easily resized but there are some that cannot (for example, most rings with stones or patterns all around).
If you have any questions please email customerservice@catbirdnyc.com before purchasing.
BEFORE MEASURING - CONFIRM PRINTED PAPER SIZE
1. Ring measurements are very precise. Carefully follow these
instructions to obtain an accurate measurement.
1 inch
2. Prior to printing, ensure that Page Scaling is set to “None” on
your print dialog box.
30 mm
3. Measure the bar on the left. It must be exactly 1 inch or 30 mm long. Alternately, place a quarter where indicated. The quarter should fit completely
over the image so that all lines are covered, without the quarter hanging over
any edges.
Measure Current Ring
1. S elect a ring that properly fits the intended finger.
(Engagement and wedding rings are traditionally worn
on the ring finger on the left hand in the United States.)
inside diameter
2. P
lace the ring over the circles below, matching the inside edge of
the ring to the circle nearest in size. This measurement refers to
the inside diameter of the ring.
3. If the ring falls between two sizes, order the larger size.
Measurements match the
inside edge of the ring.

Tips for Measuring Ring Size
MEASURING YOUR FINGER
Your ring should fit your finger comfortably; snug enough
so that it will not fall off, but loose enough to slide over
your knuckle with some resistance.
RING SIZES IN THE US
Women’s rings typically range from size 3 to 9. The most
commonly purchased women’s ring sizes at Catbird range
from size 5 to 7. Size 6 is the most popular ring size.
Finger size changes depending on the time of day and the
weather. For best results measure your finger size:
Men’s rings typically range from size 8 to 14. The most
commonly purchased men’s ring sizes at Catbird range
from size 8 to 10-1/2. Size 9 is the most popular ring size.
1. At the end of the day and when your fingers
are warm (Fingers are smaller in the early
morning and when cold.)
2. Measure finger size 3 to 4 times to eliminate
an erroneous reading.
Temperature is important
Don’t measure when your body temperature is either too cold
or too hot. A cold finger shrinks while a hot finger expands
causing an inaccurate reading. Only measure when fingers
are at room temperature.
When two sizes seem to fit
If you hesitate between two sizes, always go with
the larger one.
Don’t use strings
When measuring your finger, always refrain from
using a string, they tend to stretch, which can result
in wrong size.
Big knuckles can affect your size
If your knuckle is a lot larger than the base of your
finger, and you’re using a virtual ruler, measure both
the base of your finger and your knuckle and select
a size in between the two.
A wider band needs a bigger size
If you are purchasing a wide band, you will be
more comfortable moving up a half size from
your measurement.
TIPS FOR BUYING THE RING AS A SURPRISE
Borrow one of your signicant other’s rings (from the correct
finger) and use the ring measurements on the first page to
determine its size. We recommend measuring with a plain band.
Please make sure beforehand that the ring you are purchasing
can be resized. Rings with stones or patterns all the way around
usually cannot be resized. Most other rings can be resized for
a nominal fee.
For best results, measure a plain, narrow band
Extra wide band styles tend to run slightly small. If your
borrowed ring has a narrower shaft than the one you wish
to purchase, you may wish to order a ring a size larger than
the normal size worn. Also, large stone rings may cause the
shank to lift up when laid on its side on the display, slightly
distorting the size measurements.
INTERNATIONAL SIZE CONVERSION
If ordering from outside of the US or Canada, determine
your ring size according to your country’s standard. Then
use the International Ring Size Chart to convert to the
corresponding US ring size to place your order.
We cannot be held responsible for ring sizing. We guarantee to
make the size that is ordered, but we cannot be responsible for
conversions or fitting.
