The best big and tall flannel shirts come from Duluth Trading for sizes up to 4XL, Lands’ End for a dedicated big and tall range reaching 4XLT, and L.L.Bean for Tall sizing up to 3XL Tall. Choose by chest and sleeve measurement rather than the size label, because fits differ more at the large end of each range than in standard sizes.

Best Overall for Large Sizes: Duluth Trading Free Swingin’ Flannel
Duluth’s shirts, underwear and outerwear go up to 4XL, and its big and tall flannels include the Free Swingin’ Flannel in a relaxed fit and an untucked version. The brand’s cut is designed for movement, with extra room in the shoulders and back, which helps larger men who find regular shirts pull across the upper back. The Burlyweight option is thicker and suits colder weather.

View on AmazonThe downside is price relative to department-store brands, and the relaxed fit can feel roomy on men with narrow shoulders. Check the length measurement if you plan to wear it untucked.
Best for Tall Sleeves and Length: Lands’ End
Lands’ End offers a big and tall flannel category that reaches 4XLT. The Classic Fit Flagship Flannel and the Authentic Flannel are two options, with the Authentic listed higher in price. Both are often discounted with a promo code, so it is worth waiting for a sale. This range suits men who need extra sleeve and body length at the same time as a larger chest, which is the specific problem that regular XL shirts do not solve.
Best Classic Plaid: L.L.Bean Scotch Plaid
A fit guide reports that the Scotch Plaid in Tall sizing covers M Tall through 3XL Tall. Reviewers describe it as running slightly roomy through the chest, so if you are between sizes, take the smaller one. Note that 4XL is not confirmed for this shirt, so men above 3XL should look elsewhere.
Best Workwear: Carhartt Flannel
Carhartt’s Hubbard Plaid and Heavyweight Flannel are durable, but the guide found Tall versions only through XL Tall and 2XL Tall. Check Carhartt’s own size chart for availability above that.
Other Brands to Check
Woolrich offers 3XL big and tall flannels in secondary markets, and Eddie Bauer, J.Crew and DXL appear in fit guides. DXL specialises in big and tall sizing, so it is a useful place to compare options when other brands fall short.
How to Choose a Big and Tall Flannel
Know your measurements
Measure the chest at the fullest part, the neck, the sleeve length from the centre back to the wrist, and the torso length. Compare these numbers with the brand’s size chart. A flannel that is correct in chest but short in the sleeve will ride up when you move.
Big, tall or big and tall
Big sizes (1X to 6X) add width. Tall sizes (LT, XLT) add length. Big and tall (such as 3XLT) adds both. If you are over about 6 foot 2, go for tall sizing even at a normal chest.
Fabric weight
Lightweight flannels, around 4 to 5 ounces, suit layering indoors. Mid-weight flannels, about 5 to 6 ounces, work as a shirt-jacket. Heavy flannels, 7 ounces or more, work as outerwear.
Pre-washed or not
Brushed cotton can shrink one half-size on the first wash. Buy pre-washed or washed-down options if you have exact measurements.
Pattern scale
Big plaids can make a large frame look broader, while small checks look more even.
Decision Matrix
| Situation | Choose |
|---|---|
| Chest above 3XL and need extra length | Lands’ End Big and Tall (4XLT) or Duluth (4XL) |
| Work and cold weather | Duluth Burlyweight |
| Classic style at a moderate price | Lands’ End Flagship or L.L.Bean |
| Tall but not large around the chest | L.L.Bean Tall sizes |
Common Mistakes
The most common mistake is assuming a larger label fixes length. A 4XL adds width, but if you are tall you also need a tall cut. Another is buying a fitted flannel and expecting it to relax with washing; brushed cotton softens but it rarely gains room. Finally, many buyers forget the shirt may shrink, so order with that in mind.
Worked Example: Reading a Size Chart
Suppose you measure a 56 inch chest and a 37 inch sleeve. A 3XL typically fits chests in the mid 50s, but the sleeve may be 35 to 36 inches, so you would look at a 3XLT. If the chart lists a 4XL at 58 to 60 inches, choose it only if you want a loose fit for layering.
Care
- Wash cold and tumble on low to limit shrinkage and pilling.
- Button the shirt before washing to protect the placket.
- Check cuffs and elbows, which wear first, especially on lighter flannels.
Fabric Weight Guide
| Weight | Typical use | Season |
|---|---|---|
| 4 to 5 oz | Layering shirt | Spring and autumn |
| 5 to 6 oz | Everyday shirt or light overshirt | Autumn and mild winter |
| 7 oz and above | Shirt jacket, outerwear layer | Winter |
Who Should Look Elsewhere
If you need a size above 4XL, Duluth and Lands’ End may not cover you, and specialist retailers such as DXL are worth checking. If you are tall but slim, the Tall cuts at L.L.Bean may suit you better than a Big and Tall cut, which assumes extra width. Men who want a close fit should look at brands that offer slim or trim fits, since big and tall flannels are mostly cut loose for comfort. Finally, check the return policy, because flannel sizing and fabric weight are easier to judge in person than on a screen.
When in doubt, order the shirt in your chest size and a tall length if you have a long torso, then compare the delivered garment with your best-fitting existing shirt.
Frequently Asked Questions
What are the best big and tall flannel shirts?
Duluth Trading and Lands’ End have the widest big and tall ranges, up to 4XL and 4XLT respectively. L.L.Bean suits men up to 3XL Tall.
Do flannel shirts shrink?
Brushed cotton flannel can shrink in the first wash, especially in length. Washing cold and drying low reduces the effect.
What is the difference between big and tall sizes?
Big sizes increase width, while tall sizes add length in the body and sleeves. Big and tall sizes combine both.
Should I size up in flannel?
Not if the shirt is already roomy. L.L.Bean’s Scotch Plaid, for example, is reported to run slightly large in the chest, so the smaller size is safer if you are between sizes.
Where can I find 4XL flannels?
Duluth Trading and Lands’ End are strong starting points, and DXL is another specialist retailer for large sizes.
