Best Canning Jars. The glass is easy. The lids are the decision.
Our pick is the jar the testing was built around: standard Ball Mason jars, regular and wide mouth, with Ball or Kerr lids from a retailer you trust. Kerr, from the same maker, often covers the same ground for less. The real skill is knowing which jars and lids to walk past.

At a glance: Ball Mason Jars
Strengths
- Standard Mason-type jars match the jars USDA processing times were tested with.
- Extension services recommend Ball and Kerr lids, and replacement lids are sold everywhere.
- The jars reuse for many years; only the flat lid is replaced each time.
- Regular and wide mouth, half-pint through half-gallon, cover every tested recipe.
Limitations
- They cost more per jar than store-brand or imported jars.
- Counterfeit and look-alike lids sold online make careless reordering risky.

The verdict
Buy the standard jar the testing assumed.
The National Center for Home Food Preservation calls regular and wide-mouth Mason-type jars with self-sealing two-piece lids the best choice for home canning, and Iowa State University Extension points out why brand lists start there: USDA processing times are based on scientific testing with standard Mason jars. (NCHFP, ISU Extension)
So this is less a shootout than a map. Any standard Mason-type jar in good condition does the job. The money questions are which brand's quality you trust, where you buy lids without meeting a counterfeit, and which jars are quietly not Mason jars at all.
Top pick, the standard
Ball Mason Jars
The default for a reason: standard sizes, strong tempered glass, lids extension services recommend, and replacements in every grocery and hardware store in the country.
About $12 to $25 a dozen
Value pick, same family
Kerr
The same company and the same Mason standard as Ball, with lids extension services name alongside Ball's. Often a little cheaper, depending on region and season.
About $10 to $20 a dozen
The frugal move
Used name-brand jars
Mason jars are built to reuse for decades, so yard-sale Ball and Kerr jars are a legitimate buy. Inspect every rim for chips and the glass for cracks, and always buy new lids.
Often under $1 a jar

Why the pick wins
The jar is a system, and Ball owns the whole system.
A canning jar only works as a trio: tempered glass, a one-use flat lid with sealing compound, and a screw band. Ball wins because every piece of that trio is standard, tested, and easy to replace.
It is the tested standard
USDA process times assume standard Mason jars, and the National Center for Home Food Preservation names Mason-type jars with self-sealing lids the best choice. (NCHFP) Ball jars are the definition of that standard.
The lids are the recommended ones
When lid shortages flooded the market with look-alikes, Cooperative Extension's answer was plain: Ball and Kerr lids are what it recommends. (Ask Extension) Gaskets in unused lids stay good for at least five years, so a sensible reserve is cheap insurance.
The glass is a long-term asset
Jars reuse season after season with only new flat lids, so the per-batch cost falls every year you can. A shelf of Ball jars bought once serves a decade of harvests.
The honest caveat: for refrigerator pickles, dry storage, and fermenting, almost any sound jar works, and paying Mason-jar prices for storage glass is unnecessary. The standard matters when the jar goes into a canner.
The picks
A standard, a saver, and a yard-sale strategy.
All three run on the same two-piece lids and the same tested processes. Pick by budget and by how you like to fill a jar.
Top pick, the standard
Ball Mason Jars, Regular and Wide Mouth
Standard Mason-type jars in every tested size from half-pint to half-gallon, in regular mouth, about two and three-eighths inches across, and wide mouth, about three inches. Wide mouth fills and empties more easily with whole fruit and pickles; regular mouth lids cost slightly less. (NCHFP)
Start with a dozen pints in regular mouth for jams and sauces, add wide-mouth quarts when pickles and whole packs enter the rotation. Kerr jars are the same company and the same standard, often a little cheaper regionally.

Value pick, same family
Kerr Mason Jars
Kerr is the other Mason-jar line from Newell Brands, the company behind Ball, and its lids sit in the same extension recommendation: Ball and Kerr are the two names Cooperative Extension gives when asked which lids to buy. (Ask Extension) The glass, the sizes, and the two-piece lids are the same standard; the price is often a little lower, varying by region and season.
A note on the shelf next to it: Golden Harvest, Newell's old budget line, was announced as discontinued in 2025, though remaining inventory may still be sold. (ISU Extension) Clearance jars are fine glass if the rims pass inspection; just plan on Ball or Kerr lids going forward.

The frugal move
Used Name-Brand Jars, Inspected
Mason jars are designed to be reused for many years, which makes the yard sale, the estate sale, and the relative's basement legitimate jar suppliers. The National Center for Home Food Preservation's one glass warning applies: small scratches and nicks can become cracks and breaks under processing heat. (NCHFP)
The inspection takes seconds per jar: run a fingertip around the rim and reject any chip or nick, hold the jar to the light and reject cracks and deep scratches, and pass over antique wire-bail and zinc-cap jars, which are storage pieces now, not canning jars. Buy new flat lids; a used flat lid is never canned with again.
The inspection
What owners actually say
Jars rarely disappoint. Lids are where trust is earned.
These patterns come from canning community threads and extension client reports. A theme appears here only when multiple independent sources raise it.
Seal failures cluster on no-name lids
Iowa State University Extension reports that reliable information on no-name lids is hard to find, that reviewer comments point to lid failure as a problem, and that customer reviews of at least one import brand describe lids buckling and seals failing. (ISU Extension)
Two alternatives earn consistent praise
Among non-Newell lids, ForJars and Denali draw repeated positive owner reports for heavier metal and reliable seals. Extension services have not verified the makers' quality claims, so we treat both as promising rather than proven.
Counterfeits arrive in famous boxes
During and after the lid shortages, canners reported look-alike lids in Ball-style packaging from marketplace sellers, with thin metal and sparse sealing compound. The recurring advice in threads matches extension guidance: buy lids from a grocery, hardware, or farm store, or a marketplace listing sold by the retailer itself.
Glass breakage traces to thermal shock
When owners report broken jars, the story is usually a cold jar into hot water or a hot jar onto a cold counter, not the brand. Warm jars before filling with hot food, and set finished jars on a towel. Brand-to-brand glass complaints are rare for jars that passed a rim inspection.
The one thing to know
The flat lid is single-use. Everything else is reusable.
The sealing compound on a flat lid is engineered to soften and seal once. The National Center for Home Food Preservation's guidance runs through every part of the system (NCHFP):
- Jars: reuse for many years, inspected each season for rim chips and glass scratches.
- Flat lids: new every single time, and never a lid that is old, dented, or deformed. Unused lids keep for at least five years, and the guidance is to buy only what you will use in a year.
- Screw bands: reusable until rusted or bent, removed after jars cool and stored dry so they do not rust onto the jars.
Band tightness matters more than people expect: too loose lets liquid escape during processing, too tight keeps air from venting and can discolor the food in storage. Fingertip tight, per the lid maker's directions, is the whole technique.
How they fail, what they cost
Chips, rust, and the yearly box of lids.
Jar economics are friendly: the expensive part is bought once, and the consumable costs cents per jar.
Jars leave by chipping
The working death of a canning jar is a rim chip from clinking in storage or a dishwasher rack. A chipped jar demotes to dry storage or the fridge. Pad jars in storage and most of a batch outlives its first decade.
Bands leave by rusting
Bands stored on jars, or put away damp, rust and seize. Removing bands after sealing and storing them dry, as the National Center for Home Food Preservation advises, makes a band last many seasons. Replacements cost a few dollars a dozen.
Lids are the running cost
Plan on roughly 30 to 60 cents per lid from mainstream brands. A household canning 100 jars a year spends about $30 to $60 on lids, which is the entire annual equipment cost once jars are owned.
A failed seal is information
An occasional unsealed jar goes to the refrigerator and gets eaten first. A pattern of failures in one batch points at the lids, the band tightness, or a skipped rim wipe, in that order. Check the lid box before blaming technique.
What we didn't pick
The jars we walk past.
Reused commercial jars
Pasta sauce and mayonnaise jars have narrow sealing surfaces and less tempering. The National Center for Home Food Preservation says they produce more seal failures and breakage and rules them out for pressure canning. (NCHFP) Pantry storage, yes. Canner, no.
Metric and European jars for USDA recipes
Weck and Kilner jars are well made, but their metric sizes do not match USDA process times, which are tested on standard jar sizes. (ISU Extension) Lovely for fermenting and storage; not for the canner with a tested recipe.
Bargain no-name lid multipacks
The 300-lid marketplace bundle at a too-good price is where the reported buckling, thin metal, and seal failures live. Lids are the one part of the system where the few dollars saved risks the batch.
Antique wire-bail and zinc-cap jars
The National Center for Home Food Preservation says jars with wire bails and glass caps make attractive antiques and dry-storage containers but are not recommended for canning, and neither are one-piece zinc caps. (NCHFP)
Craft and decor jars
Jars sold for candles, crafts, and decor are not tempered for a canner, and extension guidance says to avoid lids marketed for craft or storage use. If the label does not say the jar is for home canning, it is not.
Skip the half-gallon, mostly
The National Center for Home Food Preservation says half-gallon jars may be used for canning very acid juices, and little else. They are storage glass for grains and dry goods in most pantries, not a canning workhorse.
Where it fits in your readiness
The container half of a shelf-stable pantry.
Jars belong in the Provide tier. A cabinet of sound jars and a reserve of lids is standing capacity: every harvest, sale, and batch of stock can become shelf-stable food without another purchase.
Supply interruptions
Lid shortages in recent memory emptied shelves for months. A five-year lid shelf life makes a modest reserve rational, not hoarding: a season or two ahead, used in rotation.
Power outages
Food in sealed jars does not care about the grid. Jars are also the recovery tool after an outage: a freezer thawing can become a pressure-canning weekend instead of a loss.
Maintenance
A rim check in spring, bands off in fall.
- Inspect every jar at the start of the season: fingertip around the rim for chips, glass to the light for cracks and scratches.
- Wash jars before every use, even fresh from storage.
- Remove screw bands once jars have cooled and sealed, then wash, dry, and store the bands separately.
- Store empty jars upside down or dust-covered, padded enough that rims do not clink.
- Date your lid boxes when you buy them and use the oldest first; unused lids are good for at least five years.

Questions people ask
Before you fill the first jar.
Can I reuse canning lids?
Not for canning. The National Center for Home Food Preservation says Mason jars can be reused many times, but only with a new flat lid each time, because the sealing compound is built for one use. Used flat lids are fine for storing dry goods. Screw bands are reusable until they rust or dent.
Can I reuse pasta sauce or mayonnaise jars for canning?
The National Center for Home Food Preservation advises against it in practice: commercial jars have narrower sealing surfaces and less tempering, which means more seal failures and more breakage, and they are not recommended for pressure canning at all. Mason-type home canning jars are the tested standard. Save commercial jars for refrigerator and pantry storage.
Are off-brand or imported canning lids safe?
Extension guidance is cautious. Iowa State University Extension notes USDA processing times were tested with standard Mason jars and two-piece metal lids, warns that counterfeit lids are sold online, and reports seal failures with no-name lids. Cooperative Extension has said it recommends Ball and Kerr lids. Some alternatives such as ForJars and Denali draw consistently good owner reports, but extension services have not verified the makers' testing claims. Buying recognized brands from a reputable retailer is the low-risk route.
Should I buy regular mouth or wide mouth jars?
Both work for any tested recipe that fits the jar size. Wide mouth jars, at about three inches across, are easier to fill with whole fruits, pickles, and chunky foods and easier to empty and clean. Regular mouth lids cost a little less and the jars stack a little more securely. Most households end up with regular mouth for jams and sauces and wide mouth for pickles and whole packs.
Is it safe to buy used canning jars?
Yes, with an inspection. Mason jars are made to be reused for many years, so secondhand name-brand jars are a legitimate budget move. Run a finger around the rim and reject any jar with a chip or nick, and hold the glass to the light and reject cracks and deep scratches, which the National Center for Home Food Preservation warns can break the jar during processing. Always buy new lids.
