How much does a grapefruit weigh in pounds?

Grapefruits are a delicious and nutritious citrus fruit that are enjoyed around the world. When shopping for grapefruits, it can be helpful to know their typical weight in pounds to estimate how many you may need to buy. The weight of a grapefruit can vary based on several factors, but on average, a single grapefruit weighs between 0.25 – 1.8 pounds.

Typical Grapefruit Weights

The typical weight range for a single grapefruit is:

  • Small grapefruit: 0.25 – 0.75 lbs
  • Medium grapefruit: 0.5 – 1.25 lbs
  • Large grapefruit: 0.75 – 1.8 lbs

So a petite grapefruit may be just a quarter pound, while a very large, juicy grapefruit could weigh up to 1.8 pounds. The majority fall somewhere in the middle, averaging 0.75 – 1.25 pounds.

Factors Affecting Grapefruit Weight

What makes some grapefruits heavier than others? There are a few key factors that affect the weight:

Grapefruit Variety

There are several different varieties of grapefruits, some of which are naturally larger and heavier than others. The Ruby Red and Star Ruby tend to be on the smaller side, while Pomelo grapefruits are very large.

Growing Conditions

The climate where grapefruits are grown impacts their size and weight. Grapefruits grown in very hot, humid environments with rich soil tend to produce larger, heavier fruits. Those grown in cooler climates don’t get as large.


A grapefruit’s ripeness also affects its weight. Grapefruits are harvested while still unripe and green and continue ripening off the tree. The longer they ripen, the larger and juicier they become. A fully ripe grapefruit will be heavier than an under-ripe one.

Water Content

The amount of water in a grapefruit influences its weight. Grapefruits with a higher water content and juiciness tend to weigh more than drier varieties.

Weight by Grapefruit Section

When eating a grapefruit, you don’t consume the entire fruit in one sitting. Here’s a look at the approximate weight of individual grapefruit sections:

  • 1 grapefruit section: around 1 – 2 ounces (28 – 57 grams)
  • 1/2 grapefruit (4 sections): around 4 – 8 ounces (113 – 227 grams)
  • 1/4 grapefruit (2 sections): around 2 – 4 ounces (57 – 113 grams)

Of course, the exact weight varies based on the size of the grapefruit. But this gives a general idea of portion sizes when eating grapefruit by the section.

Grapefruit Weight with and without Peel

Most people peel their grapefruits before eating them. So does the peel significantly affect the weight?

There is very little difference between the weight of a peeled vs. unpeeled grapefruit. The peel accounts for only 1-2% of the total weight.

For example, a 1 pound grapefruit with peel would weigh around 0.98 – 0.99 pounds without the peel. So the peel itself is just 0.01 – 0.02 pounds.

The minor weight of the peel means you can use the total grapefruit weight, whether peeled or unpeeled, interchangeably in recipes and nutrition facts.

How Grapefruits Are Sold and Priced

When purchasing grapefruits at the grocery store or farmers market, here is how they are typically sold and priced:


Grapefruits can be purchased individually at a fixed price per fruit. The price may vary based on size – larger grapefruits may cost slightly more. Individual grapefruits are commonly sold in plastic mesh bags.

By the Pound

Some stores sell grapefruits by the pound. This allows you to purchase the exact quantity needed without being restricted to set counts. Grapefruits are weighed at checkout and priced per pound.

Bulk Bins

At some supermarkets and natural food stores, grapefruits can be purchased from self-serve bulk bins. You select the quantity desired and they are weighed and priced by the pound at checkout.

Pre-Bagged Sets

For convenience, grapefruits are often sold pre-bagged in set counts like 3-lb or 5-lb bags. This allows easy grabbing with a set weight and price.

Typical Price per Pound

Grapefruit prices fluctuate based on season, location, and variety. On average, expect to pay between $1 – $3 per pound. Specialty varieties may cost more.

Store Price Per Pound
Walmart $1.48
Kroger $1.99
Safeway $2.49
Whole Foods $2.99

As you can see, prices are generally lowest at big box chains like Walmart and highest at premium grocers like Whole Foods.

Grapefruit Weight in Recipes

Many recipes call for grapefruit by weight instead of by fruit count. Here are some examples of grapefruit weights used in recipes:

  • 2 pounds grapefruit sections, peeled and chopped – about 4 large grapefruits
  • 1/2 pound grapefruit juice – around 1 1/4 cups or juice of 2 grapefruits
  • 1/4 pound grapefruit zest – zest of about 4 large grapefruits
  • 3 ounces ruby red grapefruit segments – about 2 segments

Using a food scale can help ensure you have just the right amount of grapefruit for recipes. Or estimate using the average grapefruit weights provided earlier.

Nutrition Facts Based on Weight

Grapefruits are packed with beneficial vitamins, minerals, and antioxidants. Their nutrition facts are often presented per 100 gram serving size:

Nutrient Per 100 g Per 1 lb (450g)
Calories 42 189
Carbs 10g 45g
Sugar 6g 27g
Fiber 2g 9g
Vitamin C 31mg 139mg

To determine the nutrients in a full grapefruit or serving size, multiply the 100g values by the weight in grams. This table shows key nutrients for a typical 0.75 pound and 1.5 pound grapefruit.

Tips for Choosing Grapefruits by Weight

Here are some tips when selecting grapefruits based on desired weight:

  • Choose larger, heavier fruits for juicing as they yield more juice.
  • Opt for petite fruits around 0.5 pounds if eating grapefruit sections as a snack.
  • Pick grapefruits that feel heavy for their size, which indicates juiciness.
  • Avoid fruits with soft spots, which signal weight loss from moisture loss.
  • Grapefruits with a deep yellow or orange color tend to be riper and heavier.
  • Buy several extra pounds if using for recipes to allow for some size variation.

Testing the weight by hand can help narrow down fruits that are around your target weight.

Weight Loss Benefits

As part of a balanced diet, grapefruits can promote weight loss:

  • Low calorie density – about 50 calories per medium grapefruit.
  • High water and fiber – fills you up on fewer calories.
  • Boosts metabolism – nutrients activate fat burning.
  • Low glycemic index – prevents blood sugar spikes.
  • Enhances fat breakdown.

Aim for around 1/2 to 1 whole grapefruit several times per week to harness these slimming properties. Consider enjoying half a grapefruit before meals to help control appetite and calorie intake.


Grapefruits range in weight from as little as 0.25 pounds up to around 1.8 pounds, with most falling between 0.75 – 1.25 pounds. Many factors like variety, growing conditions, and ripeness impact weight. When purchasing grapefruits, you’ll typically find them sold individually, by the pound, or pre-bagged in bulk. Grapefruit weight also comes into play when portioning them out for recipes and assessing their extensive nutrition benefits. With this guide, you should now have a good understanding of how much grapefruits weigh in pounds and how to select optimal fruits based on your needs.
