This thread is a compilation of the masses of different darts for reference. This information is useful for a few reasons. Some past wars have banned darts over a certain mass because these darts often are less safe. Heavier darts also have different performance characteristics: they tend to move slower, get longer range, and be more accurate. Lighter darts are faster, with shorter range, and less accuracy. You also can estimate muzzle velocities given the range, firing angle, and dart mass.

What I've compiled right now is only the beginning. I am sure I missed many dart weights and have some inaccurate figures below. Please post the mass of darts you have put on a scale before. Post the mass of the full dart, with information about each of the components if you have it. For example, a particular dart might weigh 1.35 grams, with 0.8 grams of metal weight, 0.1 grams of glue, 0.05 grams of front pad, and 0.40 grams of foam (2 inches of foam, 2.125 inches total length). If you weighed a bunch of them and know the standard deviation, that'd be useful too. Smaller standard deviations are better because consistency helps with accuracy.

Pro-tip: Don't have a scale that can measure tenths of a gram? Take a scale with less precision and put a bunch of darts on it. Divide the mass by the number of darts to get an average mass. So if your scale only has precision to the gram, put 10 darts on there and now it has precision to the tenth of a gram.


As a footnote, I was surprised by the wide variety of different dart types, and I may have mis-categorized a few types. Feel free to correct me in the comments if I've screwed up.

Edit: It might be worth mentioning that stefans in the past used to be longer, and this changes the mass a bit. Here's a poll from 2004 about dart length that you can compare to a poll from 2008. Reasons I can think of for this include the introduction of hoppers and a desire to save foam.

3/0 fishing weight glue domes. The domes are pretty flat, but whatever.

111 samples, mean 1.385586g, std. deviation .044208. None of the darts weighed were below 1.3g or above 1.5g. 1.5" long.

Got to measure some of the Megas at Apoc. 2.5 grams each.
