I was wondering is there a calculation to get a rough idea of break size? I have scripted a 3 position show, with 500g simultaneous firing and just trying to get an idea how far apart I should space them as to not over crowd the sky, but at the same time not create dead space?

Any idea on spread of standard consumer grade mortars?

I don’t know if it’s 100% accurate,, but I remember being told they go up about 100’ per inch of shell,, and break roughly half that number,, so a 1.75 consumer shell would go up 175’ and break a roughly 80’ spread

2” Mortars break around 90’ wide depending on the brand and product

In the video below, you will see 3 positions about 40ft apart and I am shooting all 1.4 or 1.4Pro consumer product. The biggest shell breaks are 62mm Dominator Pro Shells. This might give you an idea. https://youtu.be/IPZ8YLFtG6E

What did you use to fire the show? I'm using Ignite and for this years show I was thinking of having 3-5 positions. I have 6 modules and trying to determine best distance between the positions. I have a mix of 1.4 and 1.4pro as well as a bunch of 62mm.

Rule of thumb is 100’ per 1” of diameter, that is also the formula that firework simulation software uses. This formula I know for a fact is true from previous shows that I’ve done when judging the size of the front in comparison to the shell breaking at its fullest. Since a consumer shell is by cpsc rule is a maximum of 2.25” the maximum break diameter is 225’
