You've found the perfect tee. You open the size chart and suddenly you're staring at numbers and terms that do not quite make sense. What is width? Is height the shirt or my body? Why does a Large only measure 50 cm across?
This guide explains how to read a t-shirt size chart correctly, especially if you are buying international brands such as Gildan, American Apparel, and Comfort Colors. You will learn what width, length, chest, and height mean, how local Indonesian sizing compares with US sizing, and how to choose the right fit before ordering.
Why Size Charts Matter More Than Size Labels
Size labels like S, M, L, and XL are not universal. A local Indonesian L can feel very different from an international L. Brands such as Gildan, American Apparel, and Comfort Colors generally follow US sizing standards, which usually run larger than many Asian or Indonesian local sizes.
That is why the centimetre measurement matters more than the letter on the label. If you want a clean everyday fit, explore regular fit t-shirts. If you prefer a relaxed streetwear look, compare the measurements with oversized fit styles before choosing your size.
Key Size Chart Terms Explained
1. Width
Width means the garment width across the chest. It is measured when the t-shirt is laid flat, from one underarm seam to the other.
- Width is usually a half-chest measurement.
- If the width is 50 cm, the full chest circumference is around 100 cm.
- This is why the number may look smaller than expected.
Best method: take a t-shirt that already fits you well, lay it flat, measure from armpit to armpit, and compare that number with the size chart.
2. Length / Body Length
Length or body length means the measurement from the highest point of the shoulder down to the bottom hem. This helps you understand whether the t-shirt will sit cropped, regular, or longer on your body.
3. Height
Height usually refers to your body height, not the t-shirt. Some charts use height and weight together to recommend a size, but garment measurements are still more accurate.
4. Chest / Chest Width
Chest width is often the same as width. Always check whether the chart shows half-chest or full chest measurement. If it says half chest, multiply by two to estimate the full circumference.
5. Sleeve Length
Sleeve length measures the sleeve from the shoulder seam or from the center back, depending on the brand. This is more important for long sleeve t-shirts, raglan tees, hoodies, and sweatshirts.
How to Read a T-Shirt Size Chart Correctly
- Pick a t-shirt that fits you well.
- Lay it flat on a table or clean surface.
- Measure the width from armpit to armpit.
- Measure the length from shoulder to hem.
- Compare your numbers with the product size chart.
- Decide your fit preference: regular, relaxed, boxy, or oversized.
Regular, Oversized, Boxy, and Relaxed Fit: What Is the Difference?
Choosing the right size is not only about your body. It is also about the style you want.
| Fit Type | How It Feels | Best For |
|---|---|---|
| Regular Fit | Balanced, clean, not too loose | Everyday wear, layering, casual outfits |
| Oversized Fit | Loose, relaxed, streetwear-inspired | Streetwear, relaxed styling, bold silhouettes |
| Boxy Fit | Wider body with shorter length | Modern casual looks and structured outfits |
| Relaxed Fit | Slightly loose but not oversized | Comfort-focused daily wear |
If you like a modern structured silhouette, check boxy fit t-shirts. For heavier streetwear basics, explore heavyweight cotton t-shirts.

Local Indonesian Size vs International Size
International t-shirts are often wider and longer than local Indonesian sizes. This does not mean one is better than the other; it simply means the fit standard is different.
| Local Indonesian Size | Approx. International Equivalent | Fit Note |
|---|---|---|
| S | XS–S | May feel slightly roomier |
| M | S | Often similar to international S |
| L | M–L | Check width carefully |
| XL | L | May not need to size up |
If you usually wear L in local brands, you may fit M or L in international brands depending on whether you want a clean regular fit or a loose oversized fit.
Size Guide Based on Fit Preference
| Your Goal | What to Choose | Recommended Category |
|---|---|---|
| Clean daily fit | Choose your closest width measurement | Regular Fit |
| Relaxed casual fit | Choose 1 size up if you are between sizes | Casual Wear |
| Streetwear oversized fit | Choose 1–2 sizes up depending on length | Oversized Fit |
| Structured boxy look | Choose wider body with shorter length | Boxy T-Shirts |
Does Fabric Affect Fit?
Yes. Fabric can change how a t-shirt sits on your body. A lightweight tee may feel softer and drape closer to the body, while a heavyweight cotton t-shirt usually feels more structured and holds its shape better.
If you want breathable daily basics, browse mediumweight t-shirts. If you want a stronger streetwear look, heavyweight cotton is often the better choice.
Practical Tips Before Choosing Your Size
- Measure a t-shirt, not only your body. Product size charts usually show garment measurements.
- Allow small tolerance. A difference of 1–2 cm is normal in garment production.
- Size up if unsure. A slightly relaxed tee is usually easier to wear than one that is too tight.
- Check the fabric. Cotton garments may shrink slightly after washing.
- Check the fit type. Regular, boxy, and oversized t-shirts are designed differently.
