Mason Jar Size Chart

Mason jar sizes are measured in fluid ounces (oz) or milliliters (ml) and follow standard capacity designations originally established for home canning. The four traditional canning sizes are 4 oz (half pint), 8 oz (half pint), 16 oz (pint), and 32 oz (quart). Branded and promotional mason jars use these same capacity benchmarks but extend the range into smaller taster sizes (3.7 oz, 4.5 oz) and larger drinking formats (20 oz, 24 oz, 27 oz) that are not part of the traditional canning system.

TLDR: Standard mason jar sizes: 4 oz, 8 oz, 12 oz, 16 oz (pint), 24 oz, 32 oz (quart). Promotional drinkware adds 3.7 oz (taster), 15 oz, 20 oz, 24 oz, 25 oz, 27 oz. Mouth opening is either regular mouth (2.375 inches) or wide mouth (3.0 inches). The mouth opening determines which lid and decoration sticker sizes fit the jar.

For branded mason jar programs, capacity determines the use case and the imprint area. Taster glasses at 3.7–4.5 oz are used for sampling events and shots. Drinkware jars at 16 oz are the most common format for branded beverage programs. Food-fill jars at 8–16 oz hold candies, cookies, treats, or condiments. The material (glass, plastic, ceramic, silicone) and the presence of a handle or lid are secondary specifications confirmed after capacity.

Key Takeaways

• Capacity is the primary sizing input: Mason jar sizes are specified in fluid ounces or ml. The same capacity (16 oz) is available in glass, plastic, and ceramic, all with different weights, durability, and decoration options.
• Regular mouth vs. wide mouth affects lid and accessory compatibility: Regular mouth jars have a 2.375-inch opening. Wide mouth jars have a 3.0-inch opening. Standard Ball lids, straws, bamboo lids, and accessory caps are not interchangeable between the two mouth types.
• Pint (16 oz) is the standard branded drinkware format: 16 oz is the most common mason jar size for branded promotional drinkware because it holds a standard serving of beer, iced coffee, lemonade, or mixed beverages and provides enough height and circumference for a prominent imprint area.
• Promotional jars extend beyond canning sizes: Branded promotional mason jars are available in 3.7, 4.5, 15, 20, 24, 25, and 27 oz capacities that do not appear in the traditional canning size system. These sizes are designed for drinking use, not food storage.
• Glass and plastic jars require different care: Glass mason jars are typically hand wash only when decorated. Plastic mason jars (styrene, acrylic, AS, RPET) are top-rack dishwasher safe in most cases. Ceramic mason jar mugs are always hand wash only.

Standard Mason Jar Sizes

The table below covers the traditional mason jar capacity system used for canning and food storage, with corresponding dimensions and mouth type availability. These are the standard sizes referenced across Ball, Kerr, and commercial canning suppliers.

Mason Jar Mouth Types

Mason jar mouth type determines which lids, straws, caps, and accessories fit the jar. The two standard types are regular mouth and wide mouth. These specifications are standardized across all US mason jar manufacturers, so a regular mouth lid from one brand fits a regular mouth jar from any other brand.

Promotional Mason Jar Size Chart by Capacity

Branded promotional mason jars use the same capacity designations as canning jars but add taster, drinkware, and tumbler sizes that exist only in the promotional product market. The table below covers the full capacity range available in the MFG Merch catalog, mapped to product examples, materials, and primary use cases.

Mason Jar Dimensions by Product

Mason jar dimensions vary between products at the same capacity because manufacturers use different body shapes, handle placements, and shoulder profiles. The height, rim diameter, and base diameter all affect how the jar sits, how it is held, and how much imprint area is available on the body. The table below covers confirmed dimensions from the MFG Merch catalog.

Mason Jar Materials Comparison

Mason jars in the branded promotional market are available in five materials: glass, plastic (multiple types), ceramic, and silicone. Each has different weight, durability, microwave/dishwasher compatibility, and imprint options.

Mason Jar Use Case by Program Type

The right mason jar for a branded program depends on the event context, the fill or use intended, and the imprint method needed. The six primary program contexts for mason jars are drinkware, food fill gifts, sampling events, pet programs, specialty items, and sustainability programs.

Drinkware programs

For branded drinkware at events, restaurants, bars, hotels, and corporate programs, the 16 oz glass handled mason jar is the production standard. It holds a standard serving of any beverage, has a prominent imprint area on the body (typically 2.5″ x 2.5″ or larger), and reads as premium compared to a standard printed cup. Libbey-brand glass jars are the most recognized drinkware format because Libbey has been producing mason-style bar glassware for decades and the quality is consistent with branded food service contexts.

Food fill and gift programs

Food-fill mason jar programs use the jar as the packaging for a food product gift. The jar size is selected based on the fill quantity needed. The cookie and candy fills in the catalog use pint-size (16 oz) jars for 5–7 oz of product, leaving headspace for visual appeal and labeling. The mini glass jars at 2″ x 2″ x 3.375″ (used for mints, jelly beans, chocolate buttons, and Starzmania candy) are a compact desk gift format with a customizable label or imprint area on the jar exterior.

Sampling and tasting events

For tasting events, hotel amenities, wedding favors, and sampling programs, the 3.7 oz mini taster glass and the 4.5 oz sampler glass are the standard formats. These sizes hold a single tasting portion or a shot-sized beverage. The 4.5 oz format with a handle is particularly useful for tasting events where the jar is held and sipped rather than consumed in one pour.

Pet programs

Pet-fill mason jars use glass pint jars (half-pint and pint sizes) as packaging for dog treats and cat treats. The jar serves as a branded keepsake after the treats are consumed. These programs include a four-color magnet (square, paw, or heart shapes) attached to the jar as an additional branded touchpoint that transfers to the recipient’s refrigerator after unboxing.

Sustainability-positioned programs

For programs where the brand’s sustainability commitment is part of the message, specify the Bootlegger II RPET Mason Jar Tumbler (made from recycled PET plastic) or the Garyline Tritan Mason Jar (BPA-free, durable, long-life construction). Both are positioned as replacements for single-use cups and reinforce a sustainability brand message every time the recipient uses the jar.

Imprint Area by Jar Size

The imprint area on a mason jar is determined by the flat panel area on the body of the jar between the shoulder (where the jar narrows toward the lid) and the base. The wider the jar body, the larger the available imprint area. The table below provides approximate imprint area dimensions for the most common sizes in the catalog.

FAQ

What are the standard mason jar sizes?

Standard mason jar sizes for canning and food storage are 4 oz (quarter pint), 8 oz (half pint), 12 oz, 16 oz (pint), 24 oz (pint-and-a-half), 32 oz (quart), and 64 oz (half gallon). For branded promotional drinkware, additional sizes include 3.7 oz, 4.5 oz, 15 oz, 20 oz, 24 oz, 25 oz, and 27 oz formats that are designed for drinking use rather than canning.

What is the difference between regular mouth and wide mouth mason jars?

Regular mouth mason jars have a 2.375-inch opening and accept the 70/450 thread lid standard. Wide mouth mason jars have a 3.0-inch opening and accept the 86/400 thread lid standard. The lids, caps, and accessories are not interchangeable between mouth types. A quick test: if a tennis ball sits on top of the jar opening without falling in, it is regular mouth. If the ball falls into the opening, it is wide mouth.

What size mason jar is used for branded drinkware?

The 16 oz (pint) mason jar is the standard for branded drinkware programs. It holds a full serving of beer, iced coffee, lemonade, or mixed beverages and has an imprint area of approximately 2.5″ x 2.5″, which is large enough for a full brand mark with tagline. Available in glass, ceramic, and plastic formats with or without handles, lids, and straws.

Are mason jars microwave safe?

It depends on the material and the specific product. Most ceramic mason jar mugs are microwave safe. Some glass mason jars are microwave safe, specifically those with non-metallic threaded tops and no metallic decoration. Glass jars with aluminum lids or metallic imprints are not microwave safe. Plastic, AS, Tritan, and RPET mason jars are not microwave safe. The Silipint silicone mason jar is microwave safe. Always check the specific product listing before assuming microwave compatibility.

What mason jar size is best for candy and food gifts?

For candy and food fill gift programs, the most practical formats are the glass mini mason jar at 2″ x 2″ x 3.375″ (holds approximately 3.25 oz of candy, mints, or chocolate) for desk-size gifts, and the pint-size jar (16 oz) for larger fills such as 5–7 oz of cookies, treats, or dog treats. The pint jar leaves enough headspace above the fill for a decorative bow or branded label placement.
