Size Matters Blog Post

Hey there, Mason jar fans!


MJL Printable – Ink Saver (3)

One of the most common questions we receive at Mason Jar Lifestyle is about Mason jar sizes. “Will this fit on my Mason jar?!”, “Does this fit a regular Mason jar?” and also “Does this fit a normal Mason jar?” And we get it! I’ve been on your side of the computer screen before, finger poised over the Buy Now button of a pair of cute, size 7 shoes wondering, “Will these fit??” I always wear a 7… well almost always. What if this isn’t one of those times!

Don’t panic! We’ve decide to put all of your questions about regular mouth and wide mouth Mason jars to rest here in our comprehensive size guide post!

We’ve even created an awesome printable you can use at home just to be sure you’re getting the right size accessory for your Mason jar! Read down further for directions and illustrations on how to use it.

First the Basics:

Margot with half-pint Mason jarGood news! There are only TWO lid sizes for Mason jars – regular and wide mouth – and the difference between them is less than an inch.

So whether you have a 4 oz regular mouth jelly jar or a 32 oz regular mouth quart jar – the lid size doesn’t change! Pretty neat, huh?!

That means you can give your kid a glass of milk in an 8 oz (half-pint) regular mouth jar with a straw lid and metal straw and then wash and reuse the same lid with a longer straw in your 16 oz (pint) regular mouth jar with cold brewed coffee in it! So much versatility!

Also the major Mason jar brands, Ball, Kerr, and Bernardin (their Canadian brand), are made by the same parent company, Newell Brands, so you can expect consistency across the majority of the commercially available Mason jars.

These two facts will simplify your accessory shopping for sure!

Regular Mouth or Wide Mouth:

Mason Jar Lifestyle comparison of regular mouth and wide mouth Ball, Kerr, canning mason jars

Both of these a-Mason jars have a lot to offer and canners and Mason jar enthusiasts certainly have their preferences.

For me personally, it comes down to what I’m using the jar for that determines if I reach for a wide or regular mouth

So let’s compare them and then I’ll show you how to use our nifty printable guide at home.

Regular Mouth:

The regular mouth jar was the original model and measures 2 ³⁄8″ for the inner diameter and 2¾” for the outer diameter. It often has the iconic Mason jar shape (tapered top and wider at the bottom – just like me!) and is widely popular and available. You can easily score some regular mouth jars at yard sales and your favorite thrift store whenever you need to add to your collection. In generally, canners prefer a regular mouth jar for pourable foods such as sauces, jellies, and jams.

Here at Mason Jar Lifestyle, we use accessories to turn our regular mouth jars into almost anything! Below is a chart with the sizes regular mouth jars that are available and some suggested ideas:

Regular Mouth Jar Size Type With accessories, it could be used for…
4 oz jelly Snacks, dips, organization, kid-size portions
8 oz half-pint Hot & cold kids cups, crafts, sorting, pen holder
12 oz 3/4 pint Candle holder, dry goods, toothbrush holder
16 oz pint Hot & cold drinks, flower vase, soap pumps
32 oz quart Solar lights, coin banks, bug house, dry goods

Wide Mouth:

The wide mouth jar is the newer kid on the shelf and measures 3″ for the inner diameter and 3 ³⁄8″ for the outer diameter. This model has a distinct advantage in the cleaning category because it’s much easier to fit your hand and/or sponge into the opening. Canners favor wide mouth jars for whole fruits and veggies as they’re easier to fill.

Here at Mason Jar Lifestyle, the wide mouth jars get A LOT of love! We love them for drinking, making salads, and consuming leftovers. Some more ideas include:

Wide Mouth Jar Sizes Type With accessories, it could be used for…
8 oz half-pint Snacks, dips, spreads, ramekin with a lid, air freshener
16 oz pint Hot & cold cups, leftovers, to-go lunch, straw organizer
24 oz pint & half To-go smoothies, salads, hot & cold big drinks
32 oz quart Cold brewing coffee, store juice, soup, snacks, nuts, and more
64 oz half-gallon Fermentation, sun tea, dry good storage, countertop compost

Another popular questions is which jars are freezable and which aren’t. The answer is if the jar has straight sides (no tapering / shoulders) then it’s freezable. On some jars there’s a fill line marked for freezer use but the general rule of thumb is to leave half an inch (½”) of open space at the top to allow for expansion. We’ve marked which ones are freezer safe on our ink friendly printable size guide as well as our expanded versions for your convenience:MJL Printable – simple (2)

So buy those delicious treats in bulk and easily portion them out when you get home.

Whether it’s hummus, ranch, or chocolate ganache, this vessel will accommodate all your dipping needs! You can mix, transport, serve, and store all in the one container. If you’re taking it on-the-go, use a silicone sleeve for added protection (and cuteness!).

Add whimsy and rustic charm to your next gathering by serving individual portions of mac & cheese or custards in half-pint Mason jars instead of ramekins – just remember they aren’t high temperature oven safe so stick to no bake recipes like THESE.

Here at Mason Jar Lifestyle, we love using the 8 oz jar as an all natural air freshener by combine baking soda, essential oils (optional), and a cutout lid for flair and ventilation. Put one of these in your fridge, bathroom, basement, mudroom, and wherever odor lurk.

The wide mouth pint is one of our favorite jars at here at MJL (just peek in our dishwasher)! This versatile jar measures about 4 ⅝” high (a little shorter than it’s regular mouth pint jar counterpart) and is a great fit for your hand. This handy jar is probably my favorite go-to for my morning cup for warm coffee, especially when paired with a silicone sleeve and silicone drinking lid with stainless steel band. Pictured here is my coffee in our handsome faux leather sleeve with handle – another great choice! It’s also a great fit with all of our medium size straws or grab a combo pack of straight safer or thin bent straws.

Make your life easier with the wide mouth pint as it’s a great fit for putting up individual portions of homemade soup or dinner leftovers for super easy lunch packing. When I do this, I use a silicone lid liner and stainless steel band. Then at reheating time, I only need to remove the metal band and place the lid liner slightly off-center when popping my food in the microwave. Minimizes dishes and keeps the microwave clean – that’s a win/win!

If you like to keep things organized, then the wide mouth pint is perfect for keeping pens, markers, brushes, straws, and more neat and tidy – just add a frog/flower lid!

BONUS: this jar is close in height to the regular and wide mouth quart, so you can use the same size straws for both!

Are you a daily smoothie kinda person? Well the pint and a half jar has a similar capacity to many shaker bottles! You can add a ReCap lid, pour and store lid with handle, and/or smoothie straw to make your shake easy to drink and transport.

The wide mouth quart (about 6 ½” height) and regular mouth quart (about 6 ¾” height) jars are very close in size (about ¼” difference) and are pretty much the same width so you can use the same length straws (long) and silicone sleeves for both. The wide mouth quart is my husband’s go-to jar for drinking at home and the office.

Love cold brew coffee? The quart size cold brew coffee filter is my personal favorite (though we have pint and half gallon as well!). It’s so easy to brew and then strain and store in the fridge all in one jar. Try a pour and store lid with handle for freshness and easy serving.

Want to brighten up your décor with flowers? Then a wide mouth quart with a frog/flower lid makes that easy and stylish! The wide base makes it a stable vase and the wide mouth gives you lots of room for arranging.

Homemade, simple lemonade using a stainless steel juicer for Mason jars, half gallon Mason jar, organic sugar, and a pour and store lid with handle for serving.

The biggest of the wide mouth Mason jars is the half gallon measuring at 9 ⅛” tall. When you need a lot of something – this is the jar for you! I love the half gallon for parties and I make up a big batch of sun tea, fresh lemonade, coffee punch, or another festive beverage and then serve with a pour and store lid with handle.

Got a lot to pickle or ferment? Then the half gallon jar is the what you need with a glass fermentation weight, 3 piece air lock, and silicone straw hole lid.

The half gallon is also a great size for bulk dry good storage, cold brewing coffee (we have a filter for that!), countertop composting, and so much more!

We also sell extra long straws for these big beauties if you’re really thirsty in both stainless steel and glass!

Remember if it’s a Ball, Kerr or Bernardin brand Mason jar, then it’ll be a regular or wide mouth Mason jar (with very few exceptions like the “mini” jar versions – such as the Ball 4oz mini storage jar and Classico Atlas jars). Sometimes you’ll find store brands or other jars out there and they may not fit neatly into the regular or wide mouth categories so make sure you double check what brand your jar is.
