Finding the right size in XXXXL shirts can be confusing because a 4XL shirt from one brand may fit differently from another. Some shirts are designed for a relaxed fit, while others have a regular or slimmer cut. Fabric, shoulder width and shirt length can also affect how comfortable a shirt feels.
XXXXL, also written as 4XL or 4X, generally refers to an extra large clothing size beyond 3XL. However, there is no single measurement standard followed by every clothing brand.
This guide explains how to understand XXXXL shirt sizes, compare measurements in inches and centimetres and choose a suitable fit for men’s shirts, women’s shirts, cotton shirts and T-shirts.

What Size Is XXXXL in Shirts?
XXXXL is another way of writing 4XL, a plus size clothing size commonly used for shirts and other garments. It is generally larger than XXXL (3XL) and smaller than 5XL.
However, the actual fit depends on the brand and style. A 4XL T shirt may have different measurements from a 4XL formal shirt even when both use the same size label.
Before ordering XXXXL shirts online, check these measurements:
- Chest: The measurement around your body or the shirt, depending on the chart.
- Shoulder: The distance between the shoulder seams.
- Body length: The distance from the top of the shoulder near the collar to the bottom hem.
- Sleeve length: The length of the sleeve, measured according to the garment style.
The most reliable way to choose your size is to compare your body measurements with the brands size chart or compare a shirt you already own with the garment measurements.
XXXXL Shirt Size Chart in Inches and CM
The following table provides a general reference for understanding 4XL shirt measurements. These figures are approximate examples not a universal size standard. Always check the specific garment’s size chart before purchasing.
| Measurement | Inches | Centimetres |
| Body chest circumference | 58 – 60 in | 147–152 cm |
| Body chest circumference midpoint | 59 in | 150 cm |
Important: The chest range above is an illustrative fit reference, not a guarantee that every XXXXL shirt will fit a person with these measurements. It is based on one type of 4XL sizing convention. Other manufacturers may use different body size ranges.
Use the XXXXL Shirt Size Tool
Use the size tool on this page to convert measurements between inches and centimetres and make comparisons easier.
If you already know your chest, shoulder or shirt length measurement, enter it using the unit requested by the tool and convert it to the unit you need.
Remember that converting a measurement does not automatically determine your correct shirt size. Your final size still depends on the brand’s chart, the garment’s cut and how loose or fitted you prefer your shirt to be.
Gildan 5000 XXXL and XXXXL Shirt Size Chart
Gildan 5000 is a specific T-shirt style, so its measurements should not be treated as a universal size chart for every XXXXL shirt. The table below compares the larger sizes using the manufacturer’s stated measurement types.
The chest width is measured across the finished T-shirt laid flat. The full chest circumference is an approximate garment measurement calculated by doubling the flat width. Body length and sleeve length are separate garment measurements; these figures do not describe the wearer’s body size.
Use the Inches and CM options to view the measurements in your preferred unit. Always confirm the current manufacturer size chart before choosing a size.

Different T-shirt styles can use different measurement methods. Bella+Canvas 3001 and Comfort Colors 1717 measurements should therefore be displayed separately from a chart that uses fits-chest circumference.
For these styles, the flat body width is measured across the shirt while it is laid flat. Doubling this width gives an approximate garment chest circumference. It does not represent the wearer’s body chest measurement.

Body Chest Measurement vs Shirt Chest Measurement
Body chest measurement is the circumference around your chest measured with a flexible tape around the fullest part while keeping the tape level and comfortably snug.
Shirt chest measurement describes the garment itself. To measure a shirt laid flat measure across the chest from one side seam to the other using the manufacturer’s measurement method. Doubling the flat width gives an approximate garment chest circumference.
For example, a shirt measuring 30 inches across the chest when laid flat has an approximate garment chest circumference of 60 inches. However, this does not mean it will necessarily fit a person with a 60 inch body chest. The required room depends on the garment’s cut, fabric and preferred fit.
Always check whether the brand’s chart lists body measurements or finished-garment measurements before comparing sizes.
How to Measure for XXXXL Shirts
To choose the right XXXXL shirt size, measure your body and compare the results with the manufacturer’s size chart. You can use a flexible measuring tape and a shirt that already fits you comfortably.
| Measurement | How to Measure | Why It Matters |
| Chest | Wrap a flexible measuring tape around the fullest part of your chest. Keep it level across your back and comfortably snug. | Helps you compare your body chest measurement with the brand’s size chart. |
| Shoulders | Lay a well-fitting shirt flat and measure from one shoulder seam to the other. | Helps you check shoulder fit, especially for formal and button-down shirts. |
| Shirt Length | Lay the shirt flat without stretching it. Measure from the top of the shoulder near the collar to the bottom hem. | Helps you choose a shirt with a comfortable length. |
| Sleeves | Follow the manufacturer’s method. Many shirts are measured from the shoulder seam to the cuff, but measurement methods can vary. | Helps you compare sleeve length accurately between shirts. |
Compare Your Measurements with the Size Chart
Record your measurements in inches or centimetres and compare them with the chart for the exact shirt you want to buy. Check whether the chart lists body measurements or finished-garment measurements.
If possible, compare the new shirt’s garment measurements with a similar shirt you already own. If your measurements fall between sizes, consider the brand’s fit guidance, fabric and whether you prefer a closer or looser fit.
Men’s and Women’s XXXXL Shirts – Size and Fit Guide
Men’s and women’s XXXXL (4XL) shirts can differ in their cut , proportions and measurements. A men’s or unisex 4XL shirt may have different shoulder, chest and length measurements from a women’s 4XL shirt. The best fit depends on the garment style and the manufacturer’s size chart.
When comparing men’s XXXXL shirts, check the chest, shoulder width, sleeve length and body length. Formal button-up shirts may have a more structured collar and shoulders, while casual shirts, polos and T-shirts can have different cuts and garment measurements.
For women’s XXXXL shirts compare the bust or chest measurement, shoulder width, sleeve length and garment length. Fitted styles may also have waist shaping, while relaxed shirts may provide more room through the body.
Men’s and Women’s Plus Size Shirts – Sizes and Fit
Plus size shirts can include sizes such as 2XL, 3XL, 4XL, 5XL and larger, depending on the brand. These size labels do not guarantee identical measurements across manufacturers. If you need a 5XL or 6XL shirt, use the specific product’s size chart rather than assuming that each size increases by a fixed number of inches.
Fit is also important when choosing plus size shirts. Regular-fit shirts offer a more traditional shape, while relaxed or oversized styles provide a looser appearance. Tall-fit options may offer additional body or sleeve length, depending on the brand. If you need extra length, compare the garment length rather than automatically sizing up as a larger size may also change the chest and shoulder fit.
For both men’s and women’s shirts, compare body measurements with the manufacturer’s body size chart, or compare finished garment measurements with a similar shirt you already own. Make sure you are comparing the same measurement type before choosing a size.
Plus Size Shirts – Men’s and Women’s Size Guide
Plus size shirts are available in a range of sizes, including 3XL, 4XL, 5XL and larger, depending on the brand.
When choosing plus size shirts, compare chest or bust measurements, shoulder width, sleeve length and body length. Always check whether a size chart describes body measurements or the measurements of the finished garment.
Plus Size Shirt Sizes – 3XL, 4XL, 5XL and Beyond
Plus size shirts may be labelled 3XL, 4XL, 5XL, 6XL or larger, depending on the manufacturer. These labels indicate size categories, but they do not represent a universal set of measurements. A 4XL shirt from one brand may differ in chest width, shoulder width or body length from a 4XL shirt made by another.
When comparing 3XL, 4XL and 5XL shirts, use the manufacturer’s chart for the exact garment. Check whether the measurements describe the wearer’s body or the finished shirt. If the chart provides flat chest width doubling that width gives an approximate garment chest circumference.
Do not assume that moving up one size adds the same amount of room across every brand. Compare the listed measurements with your body measurements or a shirt that already fits comfortably.
How to Choose the Right Fit in Plus Size Shirts
The best plus size shirt should fit comfortably across the chest and shoulders without restricting movement. Its length and sleeve design should also suit your body proportions and how you plan to wear it.
- Regular fit: A balanced shape for everyday wear.
- Relaxed or oversized fit: Designed to provide a looser appearance and more room.
- Tall fit: May offer extra body or sleeve length, depending on the brand.
- Button-up or formal fit: Check the shoulders, collar, chest and sleeve measurements carefully.
- Long-sleeve fit: Make sure the sleeves and upper arms provide enough room for comfortable movement.
If you prefer to wear a longer shirt with leggings, compare its body length with a shirt you already own. Do not automatically size up for extra length because this can also change the chest and shoulder fit.
Cotton and Linen Plus Size Shirts – Fit and Shrinkage
Cotton and linen plus size shirts can differ in feel and fit depending on the fabric construction, weave and garment cut. Some cotton fabrics have little stretch, while cotton blends or stretch fabrics may offer more flexibility. Linen can feel lightweight but its drape and structure depend on the weave and design.
When choosing XXXXL cotton shirts or other plus size styles, check the fabric composition, chest and shoulder measurements, body length and care instructions. Some cotton garments may shrink during washing but the amount depends on the fabric, finishing and care method. Do not assume that every cotton shirt shrinks by the same amount.
Follow the manufacturer’s washing and drying guidance, and compare the garment measurements with a shirt you already own. For linen shirts, check the specific product’s measurements and care instructions rather than relying on the size label alone.
XXXXL Shirts vs XXXXL T Shirts
Although shirts and T-shirts may use the same 4XL label, their measurements and fit can differ.
| Feature | XXXXL Shirt | XXXXL T-Shirt |
| Typical style | Button down, casual or formal | Casual everyday or sportswear |
| Fabric | Often woven fabric | Often knitted fabric |
| Stretch | Depends on the fabric | Depends on the knit and fabric blend |
| Fit considerations | Chest, shoulders, collar and sleeves | Chest, shoulders, body length and sleeve opening |
| Best comparison | A similar shirt you already own | A similar T-shirt you already own |
These are general differences, not rules that apply to every garment. For example, some shirts use stretch fabric, and some T shirts have a structured fit.
If you are buying a 4XL polo shirt, compare it with a similar polo rather than assuming its measurements will match a formal shirt or a regular T-shirt.
Is XXXXL the Same as 4XL or 4X?
Yes. XXXXL, 4XL and 4X are commonly used to describe the same general size category.
However, brands may use these labels differently in their own sizing systems. The label does not guarantee identical chest, shoulder, sleeve or length measurements.
How Do I Know If XXXXL Shirts Will Fit Me?
Start by measuring your chest and comparing it with the size chart for the exact shirt you want to buy.
Next, check the shoulder width and body length. These measurements can make a significant difference even when the chest size seems correct.
If possible, measure a shirt that already fits you comfortably and compare its garment measurements with the new shirt’s chart. Make sure you compare the same type of measurement, such as flat chest width with flat chest width.
If the chart is unclear ask the seller whether the measurements refer to the garment itself or the wearer’s body.

What does XXXXL mean in shirt sizes?
XXXXL means 4XL and is generally a plus size category larger than 3XL. The exact measurements vary by manufacturer and garment style.
What chest size is a 4XL shirt?

How many centimetres is a 4XL shirt chest?
The conversion depends on the original measurement. For example, 58-60 inches is approximately 147 – 152 centimetres. Make sure you know whether the chart refers to body chest circumference or shirt circumference.
Are men’s and women’s XXXXL shirts the same size?
Not necessarily. Men’s and women’s shirts may use different cuts, proportions and measurement charts. Compare the actual garment measurements rather than relying only on the 4XL label.

Not always. T shirts and formal shirts can have different chest widths, shoulder shapes, sleeve designs and fabric properties. Compare measurements from similar garment types.
