The size of your mold determines the size of the Soap Shaper. There are a couple of steps that we need to take to guarantee our measurements are precise. Fortunately these steps are easy and all you need is a ruler or a measuring tape.
How to measure your loaf mold
Step 1: Measure the inside width
When creating smooth-over or scraper-style Soap Shapers like the Mountain Soap Shapers the most important measurement is the inside width of your loaf mold. Some mold suppliers provide this measurement on the product listing webpage, however this information is not always accurate so it is important to always double check by measuring your mold yourself.
If you use a liner with your loaf mold be sure that it is in place before taking measurements. Using a ruler or measuring tape, measure the inside width as seen below. It's always best to measure the width close to one of the ends because some molds can bow towards the middle.
How to measure your circular column mold
Step 1 (one step only): Measure the inside diameter
For pull-through Soap Shaper tools like the Kaleidoscope Soap Shaper the only measurement needed is the inside diameter of your column mold. Although some suppliers include the inside diameter on their website, any variations that occur during manufacturing can make these measurements inaccurate. Always double check by measuring your mold yourself.
To measure the inside diameter of your column mold place a ruler or measuring tape across the open end and line it up with the widest point. The inside diameter is the distance across the middle of the mold, not including the thickness of the mold walls.
Repeat these steps and measure at the point perpendicular to your previous measurement in a cross format. If the measurements are different, use the narrower of the two as the diameter of your mold.
Look for the PVC pipe markings
PVC piping is often used as molds for soap making. The nice thing about PVC pipe is that the size is named after the inside diameter. This means that 3 in PVC piping has an inside diameter of 3 in (give or take 0.5 mm due to imperfections during manufacturing). One way to identify the size is to refer to the pipe markings which are printed on the outside of the pipe. The size is usually listed after the manufacturer's name and is measured in inches.
Accurate measurements are essential in creating the perfect sized Soap Shaper for your mold. With this in mind the measurements you provide are always checked against the size you select and the other information you share during the order process, like website links and mold specifications. If any inconsistencies are noted we will be in touch to confirm the details before your order goes into production. That way we can be sure that the Soap Shaper design tools we create for you are the perfect size.

Hi, I came to you by way of a YouTube soap video. I’m about to purchase your kaleidoscope pull through tool. I see your pvc tube molds and I love the idea but I’m curious, how do you get the soap out? I imagine it’d be super resistant to de-molding. Thanks! Anne
Hi Anne, Thanks for stopping by. Gelling your soap is recommended, but not absolutely necessary. It will help with unmolding your soap sooner. If you don't gel your soap or if it's still a bit sticky you can either wait an extra day or 2 or pop the mold in the freezer for 15-30 mins to assist with unmolding. Then you can use a round cylindrical item that is slightly narrower than the inside diameter of the mold (like a can, jar or canister) to push down on the get the soap moving through the mold. I use the bottom of one of these (smaller one: https://www.tournaire.fr/wp-content/uploads/2014/10/system-plus1.png) because the surface is nice and smooth and it fits inside the mold nicely. I find this works really well and is very easy to do just using my body weight. A full set of instructions is also included with every order to provide guidance through each step of the process. All the best and I hope this helps!
