Hammond Enclosure Finder for DIY Guitar Pedals (with Dimensions)
As you probably already know, Hammond 1590-series enclosures are the most common enclosures used in DIY guitar pedal projects. I don't know about you, but it's always been a hassle trying to figure out which enclosure a new circuit will fit into.
I put together the below directory and enclosure finder tool to make the process of selecting an enclosure MUCH easier. I pulled all the dimensions from the Hammond datasheets, but if any of them are erroneous, and you happen to know them, feel free to contact me and I'll update the list.

Enclosure Finder: Will It Fit?
Do you already have a circuit board and you're looking to see which enclosures it will fit? Use the calculator below to find a list of enclosures that will fit your particular circuit board.
Just punch in the Length and Width of the circuit board, then click Find Enclosures to view a list of worthy enclosure options. If your board is shaped like a square or rectangle, then check the Include Screw Clearance options to ensure that the board will fit between the screw columns. You can change the units (either inches or millimeters) and sort the results based on size (large to small, or vice-versa).
Note that this tool is an approximation and is meant to get you close to a possible enclosure solution. There is a drawing PDF file that appears for each enclosure, you can use that to compare the dimensions and double-check the results. Happy building!

Meet the Author:
Hi, I'm Dominic. By day, I'm an engineer. By night, I repair and modify guitar effects! Since 2017, I've been independently modifying and repairing guitar effects and audio equipment under Mimmotronics Effects in Western New York. After coming out with a series of guitar effects development boards, I decided the next step is to support that community through content on what I've learned through the years. Writing about electronics gives me great joy, particularly because I love seeing what others do with the knowledge they gain about guitar effects and audio circuits. Feel free to reach out using the contact form!
