What to Look for When Shopping for a Scale

When you want to specifically weigh weed, there are a few key factors to look out for to make sure that your scale will serve your needs long term.

Scale Type

Aside from the digital scales we mentioned here, you can opt for other types of scales if you’re looking for a more old-school addition to your grow space. When shopping for a weed scale, you might come across the following types:

1. Traditional AWS Scale – These traditional American weigh scales (AWS) are normally made of cast iron with separate weights. This type of unit may have pivot and steel bearings for accuracy, strength, and hygiene, but has a limited weight range and is not ideal for accurately weighing weed.

2. Mechanical Scale – These scales feature a number dial, and some types have a rotating weight gauge, which can be reset to zero. These scales can easily become un-calibrated which could skew your measurements if you don’t recalibrate them regularly.

3. Digital Scale – A digital scale, like the ones on this list, is handy for precision measuring. Most digital units have a tare feature that automatically subtracts the weight of the container you use, making them a perfect choice for weighing weed.

Display

Weighing scales usually feature either an analog or digital display. Analog displays are round and have dials that you have to read to determine the exact weight scale. Digital scales are fitted with a backlit LCD display screen that shows viewable numbers that you can easily decipher. Units with a digital display must read zero before each use. Digital scale readouts show weight in a matter of seconds and have much higher accuracy than analog scales.

Portability

Depending on the size and capacity of your grow space, you may need a scale that can move around with you, and be small enough to live in your grow area. Most of the scales on our list can be described as stealth scales because they are small and discreet, and not obviously used for weighing marijuana.

Weight Capacity

When it comes to weighing weed, a scale with an 11-pound maximum and an option to switch from ounces to pounds and grams to kilograms is a good choice. Units with substantial capacity and capable of weighing from 0.1 grams are normally most effective. They normally have high-precision sensors to display accurate readings.

Accuracy, Resolution, & Precision

  • Accuracy refers to how close the displayed weight is to the actual weight of the weed you are measuring.
  • Resolution is the lowest increment of the weight that can be displayed or detected on the scale. Normally, a resolution is highly affected by the digits (precision) that are exhibited on the display when weighing something. Resolution can be affected by scale design, wear, and friction. So, you have to factor all these to get a high resolution reading.
  • Precision refers to the number of decimals your scale can display, making it one of the most important factors to consider when shopping for a portable scale. A precision scale offers confident readings. Not to mention that it is remarkably easy to decipher.

Units of Measurement

Depending on the quantity of weed you’re growing, you need to find a scale that can accommodate the units of measurement that you’ll be using. Most digital scales have settings to choose between American units (ounces, pounds, and tons) and Metric units (milligrams, grams, and kilograms).

Try to choose a scale that can measure in pounds, ounces, grams, and kilograms. The smaller the unit of measurement, the more accurate your numbers will be.

Final Thoughts

Choosing a weed scale might not be high on your priority list when growing marijuana, but choosing the right one can save you tons of time and headache. When you’re already investing time and money into making your grow space the best it can be, there’s no reason to cut corners on something as simple as a scale.

We hope that by outlining some of our favorite weed scales, you can choose the right one to make your life just a little bit easier while you’re tending to your plants.

The 5 Best Weed Scales for Taking Measurements (and Controlling Portions)

More precise measurements than your standard kitchen scale, that is.

When doling out weed, there are two main schools of thought. One leans on the judiciousness of “eyeballing it.” The other adheres to empirical evidence. Since you’re here, browsing for a scale to measure out loose (as in, not in concentrate form) cannabis, we’ll assume you favor the STEM approach. It’s a good one. It makes portion control, whether for grinding and vaping or baking into meals, more manageable. For medical marijuana users especially, dosage matters. Should you be paranoid that your dealer, dispensary, or buddy is shorting you, a scale will tell you what’s really up. And in legal states where there are weight limitations on how much marijuana you can possess, a scale can help you stay above the law.

Weed scales aren’t marketed as “weed scales,” because really, they’re just kitchen scales or jewelry scales that have certain useful features. One is the ability to measure in hundredths of grams, which is more precise than many kitchen scales. Rounding to the nearest gram might not matter much if you’re weighing rice, but the difference between a quarter of a gram of cannabis and full gram is definitely noticeable. But a scale should be able to handle different types of measurements outside of weed, which is why all the scales here are able to convert to units beyond your standard weed units of grams and ounces. The first four scales are also equipped with a Tare function, meaning you can measure the weight of the cannabis in a container in a way that negates the weight of the container itself.

And now, onto the scales themselves, each of which is best for a slightly different kind of weed-ingesting lifestyle. Pair one with responsibly and fairly grown product—seriously, be a conscious consumer in this realm, because its rife with inequalities—and a fresh pack of AAA batteries. No USB-C cords to be found here.

For no-fuss, everyday use, this Brifit scale is a strong contender. It measures in .01 gram increments up to 500 grams—though it won’t correctly read the weight of anything below .05 grams, so be aware if you’re working with tiny portions. The two plastic trays it comes with, one of which is slightly smaller than the other, are removable and washable, so if you’re interested in using the scale for items that don’t produce highs, there won’t be cross-contamination. And at five-inches by four-inches, it won’t hog counter space. (If red doesn’t vibe with your energy or whatever, the base also comes in black and silver.) Takes AAA batteries.

Another Brifit scale, this model flips open to reveal a small platform and LCD screen, then closes right back up so you can stick it in a bag or tuck it away in a drawer until weed must be measured again. In other words, it’s the same price and measures to the same .01 grams of accuracy—although it’ll read anything above .03 grams, and it comes with a calibration weight—but for a different lifestyle. After all, with its industrial look, it’s not exactly the type of appliance we’d recommend you display next to the Smeg blender and the KitchenAid mixer; and the other color options are just as vibrant. Takes AAA batteries.

One of the most precise scales you can choose—and if you’re one for nit-picking, then in all likelihood you will choose it—the Gemini measures whatever is in its cup to .001 grams of accuracy, but maxes out at 20 grams. And with the shield that flips down over the scale, even a huff of air won’t disrupt the measurement of the smallest tuft of weed. Beyond the pinpoint accuracy, this scale comes with that removable cup, which can be a blessing for less dextrous fingers, and two calibration weights to keep it accurate. The longest side is five inches across, and made with sturdy stainless steel, you can take it outside the house with few worries. Takes AAA batteries.

The larger scale on this dual set-up holds and measures up to a whopping (relatively speaking) 11 pounds. Do you have that much weed to weigh? Seems unlikely, but we don’t know you. It’s the smaller scale that’s perfect for weed-related tasks, as it measures in .01 gram increments; the scales can work in tandem or separately. As a package, this scale is downright handy for people who spend time in the kitchen, following recipes (THC-containing or otherwise) and taking measurements big and small. Give it a dedicated spot on the countertop. Takes AAA batteries.

This scale is practically a novelty item, but useful nonetheless. While there’s nothing illegal about a scale in and of itself, weed is iffy. And so this scale, disguised as a flip-top lighter and only three-by-two inches big, can lend you some secrecy. It’s not exactly a fine-tuned piece of machinery, but it’ll get you close-enough measurements to the a hundredth of a gram, up to 100 grams, and it comes with a plastic platform you can pop onto the scale to give you more room to work. Takes CR2032 batteries.

Weed scales are really just digital kitchen scales that have certain useful features. These five are some of the most accurate for portioning out cannabis every day. ]]>
