the same way you measure smoke.
wheigh your bottle of soapy water a balance that goes out to 4 places. blow your bubble and wiegh your bottle again.

Place the liquid in a flat sided container with a ruler or grid behind it, side light the liquid to make the bubbles stand out and photograph the bubbles from a bit of a distance away to reduce parallax then measure the diameter in an enlargement of the image.
If you must measure the bubbles in place in a clear liquid, take a short piece of ruler or grid, mount it on a stick or rod and lower it into the solution near the bubbles (again sidelighting really helps) and photograph the bubbles and ruler together. While the image size will be distorted by the liquid/air or liquid/glass/air interface, since the ruler is in with the bubbles it will be distorted the same amount as the bubbles and thus give you an accurate measure.
If the bubbles are really, really tiny, then use music wire, which you can get in 3' lengths at hobby and some hardware stores, which comes in very accurate sizes like 0.001, 0.010, etc. (or you can measure any wire with a micrometer) and put it in near the bubbles. Enlarge the photo sufficiently so you can measure the sizes of the enlarged bubbles and wire and use ratios to get the bubble size from the wire size.

Well if you really need to measure a bubble you could get a bottle of liquid dish soap shake it up, then let it set a minute so the bubbles settle at the top, take a ruler centimeter side and estimate the size by placing the ruler by the bubble your looking at. There should be several sizes to choose from.

Can you remove a single bubble (or perhaps just a few)? If so, first measure the volume of the liquid. Then remove a single bubble. Then measure the volume of the liquid again. The difference is the volume of the bubble (or bubbles) that you removed.
If the liquid is in a pipette, or similar lab equipment, sometimes you can remove bubbles by tapping the side of the container. If you can count the number of bubbles that were released, then you can estimate the volume of each bubble.
Difference in volume / # of bubbles = average volume of each bubble

u cannot measure it, can u measure water in centimeters? or can u measure air in inches? no
