How Much Do Coffee Mugs Weigh?

Most coffee lovers reach for their favorite cup first thing in the morning since it is crucial to preparing coffee. 

Although there are many different types of mugs, most manufacturers stick to a standard size as far as dimensions are concerned.

A standard porcelain coffee mug can weigh between fourteen and nine ounces without coffee.

Its size can range from thirty-one fl. oz. with 4.1 x 8.6 inches to eight fl. oz. with 2.75 x 3.15 inches, depending on how much coffee it can hold.

Weight of a Coffee Bean

A coffee bean typically weighs between 120 and 170 milligrams, or 0.12 and 0.17 grams. This is somewhat more than one-tenth of a gram. Hence 6 to 10 beans make up one gram. 

This also provides us with the average coffee bean weight, approximately 145 milligrams or 0.145 grams. However, the precise weight of a single coffee bean will vary depending on various variables.

For example, every coffee bean will not grow out to be the same size. There will be some tiny variations in size and weight because of different growth rates and the development of the parent plant.

Not to mention, the size will also depend on the amount of water the coffee beans receive. Healthy coffee plants will produce larger beans that will weigh more. 

Additionally, different coffee plant types may yield beans that are a little bit different in terms of weight and size. What’s more, drying might also affect their size and weight. 

With that out of the way, let’s move on to the next factor: The weight of 8 ounces of freshly brewed coffee.

Weight of 8 Ounces of Freshly Brewed Coffee

A typical coffee drinker will drink an average of 8 ounces of freshly brewed coffee per cup. As far as how much these 8 ounces weigh, here’s the answer. 

8 ounces of freshly brewed coffee weighs around 227 grams or 0.5 pounds. So, when you add this liquid to your favorite coffee mug, you also have to account for its weight. 

For example, if you pour 8 ounces of coffee into a stoneware coffee mug, you will have to add 0.5 pounds to the mug’s weight to get the total weight. 

The same is also the case when pouring 8 ounces of coffee into glass, ceramic, stainless steel, and porcelain coffee mugs. 

Just add the weight of the liquid to the weight of the mug to get the total weight. 

Average Weight of Coffee Mugs 

Typically, coffee mugs are constructed of ceramic or porcelain. Porcelain or ceramic mugs usually weigh between 0.5 and 0.8 pounds due to the relative lightness of these China-like materials.

Furthermore, some mugs are larger because some people want a larger cup of coffee to get them through the day.

On the other hand, some mugs are smaller because they are designed for small amounts of coffee, like an espresso shot. Ultimately, larger cups will inevitably weigh more than smaller mugs.

While most coffee mugs are made of ceramic or porcelain, they can also be made of stainless steel, glass, stoneware, or even melamine, a durable, reusable plastic.

Each of these materials has a distinct weight, so the average weight of a coffee cup manufactured from each material will be different. However, this all depends on the material used. 

For example, coffee mugs made of glass are typically heavy. Because of how they will be used, glass mugs are often much thicker and more robust than other mugs. 

However, the thicker the glass, the more the mug will weigh. In contrast, Stoneware mugs are the heaviest mugs around.

In addition to being slightly larger than a standard coffee mug, stoneware mugs are also composed of denser, heavier material.

Full vs. Empty Coffee Mugs

While ceramic coffee cups can become hefty when filled with liquid, their average weight makes regular coffee mugs seem rather light.

The precise liquid weight depends on what you put in your coffee and how much the mug can hold. The standard coffee “cup” size does not always match the standard imperial cup unit of measurement.

The liquid inside coffee mugs typically weighs between 177 and 237 grams in standard mugs or 6 to 8 fluid ounces. Denser liquids, such as hot cocoa, will weigh slightly more than eight ounces of water.

Because it is still a thin liquid, your preferred drip coffee doesn’t weigh all that much more than water.

If you add cream, milk, sugar, or other additives, the liquid in your normal-sized coffee mug could make it heavier.

Weight of Travel Mugs

Because they are designed for a specific purpose, travel weights and sizes can vary compared to a traditional coffee mug. 

Compared to normal coffee mugs, tumblers of travel mugs often have a different shape altogether and are more typically made of stainless steel or plastic.

The most popular types of travel coffee mugs or tumblers are stainless steel and range in weight from 310 to 380 grams or 0.77 to 0.92 pounds.

On the other hand, plastic travel mugs can only hold cold beverages such as iced coffee. 

The materials used to make these travel coffee cups are far thinner than the insulating materials used to make stainless steel travel mugs. After all, their job is not to retain heat but to keep your beverage cold.

Weight of Starbucks Ceramic Coffee Mugs

Coffee can be poured into Starbucks ceramic coffee mugs ranging from 470 ml to 350 ml at any given moment. These Starbucks ceramic coffee mugs typically weigh around 450 grams or one pound.

A 16-ounce Grande plastic iced coffee mug is around 0.02 or 9 grams. However, the weight of a Starbucks plastic cup varies according to its dimensions as well.

There are a total of 6 available sizes for Starbucks plastic coffee cups. These include Trenta (30 fl. Oz), Venti (20 fl. Oz), Grande (14 fl. Oz), Tall (12 fl. Oz), Short (8 fl. Oz), and Demi (3 fl. Oz). 

Factors Affecting Coffee Mug Weight

The specific weight of a coffee mug depends on various factors. The amount of liquid it can hold and the type of materials used are the two features of a coffee cup that are most crucial.

Here is a detailed explanation of what we mean:


The standard coffee mug is made of ceramic, with a capacity of nine to twelve ounces and measurements of roughly 3.25 by 3.75 inches. However, is that the ideal size? Not necessarily. 

No matter how much coffee you prefer to drink, the “ideal” cup for your morning cup of Joe can be filled to your desired amount of coffee.

Some people believe that drinking too much coffee depletes their vitality, while others can’t get enough of the stimulant.

So, the best coffee mug for you is one that can hold just the right amount of coffee. In light of this, here are a few tips to consider when choosing the perfect coffee mug:

  • If you want to buy numerous coffee mugs for home or office use, go for smaller ones.
  • Which coffee-based drink do you most frequently consume? For instance, espressos frequently come in quantities of around two fluid ounces, compared to drip coffee’s six fluid ounces.
  • Large coffee mugs are more awkward to hold and bulkier. 
  • If you like to consume your coffee on the go, think about purchasing a smaller mug or a travel mug that fits in your vehicle’s cup holder.
  • High-quality coffee mugs will keep your beverage hot for a long time, allowing you to enjoy a hot cuppa for hours.
  • Your coffee mug must be able to fit underneath your espresso machine’s nozzle or spout.


There isn’t just one perfect material for a coffee mug. Here are a few widely-used coffee mug materials and their respective weights:

  • Stoneware: holds 17 to 24 ounces and weighs 1 to 1.5 pounds when empty
  • Stainless steel: holds 11 to 14 ounces and weighs 0.7 to 0.8 pounds when empty
  • Porcelain: holds 9 to 14 ounces and weighs 0.5 to 0.8 pounds when empty
  • Glass: holds 8 to 23 ounces and weighs 0.52 to 1.45 pounds when empty
  • Disposable Plastic: 0.29 to 0.6 ounces and weighs 0.02 to 0.05 pounds when empty

A porcelain coffee mug typically weighs between 9 and 14 ounces, while a stoneware coffee mug weighs between 17 and 24 ounces, or about twice as much.

These ratios are appropriate for coffee mugs containing 2 to 14 fl. Oz of coffee.

However, the Trenta, the largest serving size offered at well-known coffee shops like Starbucks, may hold up to 31 ounces. 

Wrapping Up

Your coffee mug’s dimensions, size, materials, and the type of liquid poured into it significantly impact your favorite coffee mug’s weight.

The denser the liquid and heavier the mug, the more it will weigh when full. Furthermore, if you prefer to take creamer, milk, or sugar with your cup of Joe, you will add more weight to the mug. 

It’s your choice which material you go with and what type of beverage you enjoy. Ultimately, it’s all about purchasing a coffee mug that’s comfortable to hold with excellent heat retention qualities.
