Getting accurate weed measurements is helpful when harvesting buds or making edibles. However, if your scale is not calibrated or doesn’t have the right features, precision, or capacity, you may be getting inaccurate measurements. Here's how to pick the right weed scale.

What Is a Weed Scale?

Weed scales are mechanical or digital instruments that accurately weigh dry goods and liquids, including cannabis flower, trim, or infused products. Scales can Weigh an object’s weight in U.S. customary and metric units. Many models are affordable and portable.

Why Invest in a Weed Scale

A weed scale can revolutionize how well you extract concentrates and cook with cannabis. Estimating amounts won't produce consistent results. Only a well-calibrated scale can show you the exact amount you're working with.

Here are a few reasons why investing in a reliable scale is a must:

  • Avoid possessing cannabis over the legal limit
  • Verify the weight of purchased cannabis
  • Split cannabis between others
  • Determine the total yield after harvest
  • Weigh ingredients in the kitchen
  • Determine edible dosage

Can I Use My Kitchen Scale to Weigh Cannabis?

Kitchen scales may get the job done in a pinch, but they may not offer the level of precision you need to weigh weed. Scales for weighing cannabis usually can weigh down to 0.1 grams, while kitchen scales weigh down to the gram. Kitchen scales may also not have other functions. 

Factors to Consider When Buying a Weed Scale

Finding the right weed scale can take some time and patience. Consider the following factors to find the best weed scales.


Cannabis-friendly scales are usually made out of heavy-duty plastic or stainless steel. We recommend going with one made primarily of stainless steel, although it may have plastic components. Stainless steel provides better durability and longevity.


Weed scales have varying levels of precision, weighing down to 0.1, 0.01, or 0.001 grams. For most users, an precision of 0.1 gram provides the best value. 

A scale with a 0.1-gram precision can experience a maximum loss of just 1/20 of a gram from the margin of error compared to losses of up to ½ a gram when using scales with a one-gram precision.

Scales weighing down to 0.01 grams have a maximum loss of 1/200 of a gram, which can be helpful when weighing small things like cannabis concentrates. 


Will you be using your scale for on-the-go weighing or more at home or in a commercial facility? This can determine whether you need portable and discreet pocket scales or high-capacity scales for commercial purposes. Most users can get by with a pocket scale. Commercial cannabis facilities will need a larger scale.


A tare function allows you to place an object on the scale’s surface and zero it out so you can eliminate the weight of the container and just measure the weed.

The overload protection function on a digital weed scale prevents it from getting damaged. The overload protection will display an error message if you exceed the scale's capacity.

Make sure your scale can measure in your desired units, whether metric or U.S. customary. Small amounts of cannabis are measured in grams, while larger quantities are measured in ounces and pounds.


How much weed do you plan to weigh? Include the container weight in your calculations. Generally, scales with a higher precision tend to have lower capacities than scales with lower accuracy. Stick with a scale with a maximum weighing capacity of 100 to 200 grams if it's just for personal use.


Avoid getting stuck with an ineffective marijuana scale and go for one with an ironclad warranty. Some manufacturers offer up to 10 years of warranty, while others provide a more moderate 1, 3, or 5-year warranty.
