For DIY purposes I’ll say a “precision” scale is one that can weigh down to 0.01g (0.00035 ounces). Scales this precise often have a fairly low maximum weight (100–200g) so they are best suited for smaller batches of products, or for weighing out potent ingredients like preservatives before incorporating them into larger batches of products. Remember that the maximum weight of a scale includes the weight of your container! You definitely can get precise scales with higher maximum weights, but as the maximum weight goes up, so does the price.

I highly recommend picking up some sort of precision scale if you enjoy this hobby. I started with an inexpensive one (often sold as jewellery scales) from Amazon: Smart Weigh SWS100 Elite Pocket Sized Digital Scale, Black. After breaking a few of these I upgraded to the Jennings JSR-200 (USA / Canada), and I’ve been very impressed with it. It’s lasted a lot longer than the Smart Weigh ones ever did, and the extra 100g of maximum weight is useful.
As of summer 2020, I also have a Jennings TB 500—this lovely scale weighs up to 500g at 0.01g increments, and it also plugs into the wall so auto shut-off isn’t an issue! I purchased mine from CanadianWeigh, but as of 2026 they no longer carry it. You can still purchase it here in the USA.
For Canadian options as of summer 2026, the ProScale XC 501 and ProScale CTS 600 look like decent alternatives to the Jennings TB 500Jennings TB 500 (I haven’t used either).
