Choosing the right women’s long sleeve tee size becomes much easier when you stop relying only on letters like S, M or L and start with your actual measurements.
The most important measurement is usually your bust, but sleeve length, body length and the intended fit of the tee can also make a big difference.
Women’s Long Sleeve Tee Size Chart
Use this chart as a general starting point:
| Size | Bust |
|---|---|
| XS | 31–33 in (79–84 cm) |
| S | 34–36 in (86–91 cm) |
| M | 37–39 in (94–99 cm) |
| L | 40–42 in (102–107 cm) |
| XL | 43–45 in (109–114 cm) |
| XXL | 46–49 in (117–124 cm) |
These measurements are general guidelines, not universal standards. Different brands and cuts can fit differently, so always check the size chart for the specific product you want to buy.
How to Measure Your Bust Correctly
Use a soft measuring tape and wrap it around the fullest part of your bust.
For the most accurate measurement:
- keep the tape level around your body;
- do not pull it too tightly;
- stand naturally and breathe normally;
- measure over a thin top or directly over the body.
Once you have the number, compare it with the bust ranges in the size chart.
Why Sleeve Length Matters
A long sleeve tee can fit perfectly around the bust and still feel wrong if the sleeves are too short or too long.
For a classic fit, the sleeves should usually finish around the wrist bone. They should stay comfortable when you bend your arms without pulling strongly upward.
If you have longer or shorter arms than average, always check the garment’s sleeve measurement when it is available.
How Long Should the Tee Be?
For a regular fit, a women’s long sleeve tee usually finishes around the upper hip area and comfortably covers the waistband.
Cropped styles will naturally be shorter, while oversized tees are often longer and wider. The correct length depends on the design, not only the size label.
What If You Are Between Two Sizes?
If your measurement falls between two sizes, think about how you want the tee to fit.
- Choose the smaller size for a more fitted silhouette.
- Choose the larger size for more room, layering or a relaxed feel.
If the product is already designed as oversized, you usually do not need to size up just to get a loose look.
Fitted, Regular, Relaxed or Oversized?
The same size can look completely different depending on the cut.
- Fitted: follows the body closely through the bust, waist and arms.
- Regular: offers a balanced fit with comfortable room.
- Relaxed: has more space through the body and sleeves.
- Oversized: is intentionally wider and often longer, usually with dropped shoulders.

Best Way to Choose Your Size Online
One of the easiest and most reliable methods is to compare a new tee with one you already own and love.
Lay your favorite long sleeve tee flat and measure:
- the width across the chest;
- the body length;
- the sleeve length.
Then compare those measurements with the product size guide. This is often more accurate than choosing a size based only on your height or weight.
Quick Answer
What women’s long sleeve tee size should you choose? Start with your bust measurement. As a general guide, women’s sizes commonly range from approximately 31–33 inches for XS to around 46–49 inches for XXL.
But the best size is the one that matches your measurements, your body proportions and the intended fit of the tee. Always check the specific product size chart before ordering.
