Nominal Width • Inches • Girth • Fit
A 58 mm condom normally means the condom has an approximately 58 mm nominal width when laid flat. That equals about 2.28 inches from side to side. Learn what the number actually measures, whether 58 mm is considered large or XL, how it compares with 56, 57, 60 and 62 mm condoms, and why it should not be confused with penis girth.
Doubling 58 mm gives 116 mm or about 4.57 inches of simple unstretched flat-tube geometry. That number is not an automatic penis-girth recommendation.
When a condom manufacturer lists 58 mm, the measurement usually refers to the condom's nominal width.
Nominal width is the width of the condom when it is laid flat and measured from one side to the other.
It does not mean the condom is intended for a penis that measures 58 mm in circumference, and it does not mean the penis should measure 58 mm in diameter.
Instead, 58 mm is primarily a technical product measurement that lets you compare one condom with another more accurately than broad package labels such as regular, large, XL or XXL.
Rounded to two decimal places, a 58 mm nominal-width condom is approximately 2.28 inches wide when flat.
Imagine an unused condom laid flat on a table.
Instead of measuring all the way around the condom tube, nominal width is measured straight across the flattened condom.
If that measurement is 58 mm, the product may be described as having a 58 mm nominal width.
The stated flat side-to-side condom measurement.
The same width expressed in centimetres.
The same nominal width expressed in imperial units.
Body circumference is measured separately around the erect shaft.

Because one inch equals exactly 25.4 millimetres, the conversion is simple.
Therefore, 58 mm is normally rounded to approximately 2.28 inches.
If the condom package displays measurements in millimetres but you are more familiar with inches, 2.28 inches is the useful equivalent to remember.
That number still describes the flat condom width, not penis diameter.
A tubular condom flattened on a surface creates two layers of material.
For simple geometric comparison, doubling its 58 mm nominal width gives:
This is useful for understanding the unstretched geometry of a simple flat tube.
A 58 mm nominal width generally sits in the larger or wider part of the condom-size spectrum.
It is wider than many common regular condoms, which frequently sit in the low-to-mid 50 mm range depending on the manufacturer.
However, there is no universal law saying every 58 mm condom must be labelled “Large” or “XL”.
One manufacturer may call approximately 57–58 mm “Wide”, another may call it “Large”, and another may include it within an XL product family.
This is why the technical nominal-width number is more useful for comparisons than the marketing label.
A useful way to understand 58 mm is to place it beside neighboring nominal widths.
| Nominal Width | Width In Inches | Doubled Flat Width | Doubled Width Inches | Broad Position |
|---|---|---|---|---|
| 54 mm | 2.13" | 108 mm | 4.25" | Regular Example |
| 56 mm | 2.20" | 112 mm | 4.41" | Regular / Roomier |
| 57 mm | 2.24" | 114 mm | 4.49" | Wide Example |
| 58 mm | 2.28" | 116 mm | 4.57" | Large / Wide |
| 60 mm | 2.36" | 120 mm | 4.72" | Wide |
| 62 mm | 2.44" | 124 mm | 4.88" | Wide / XL |
| 64 mm | 2.52" | 128 mm | 5.04" | Extra Wide |
The difference between a 57 mm and 58 mm condom is only 1 mm in nominal width.
57 mm converts to approximately 2.24 inches, while 58 mm converts to approximately 2.28 inches.
That means the difference across the flat width is only about 0.04 inches.
Despite the small numerical difference, materials, shape and elasticity can make two condoms feel more different than the one-millimetre width change alone suggests.
Current Durex Wide Fit products, for example, use a 57 mm nominal width, while 58 mm appears in other larger product ranges.
A 60 mm condom is 2 mm wider than a 58 mm condom when laid flat.
| Measurement | 58 mm | 60 mm | Difference |
|---|---|---|---|
| Nominal Width | 58 mm | 60 mm | +2 mm |
| Width In Inches | 2.28" | 2.36" | ≈ 0.08" |
| Doubled Width | 116 mm | 120 mm | +4 mm |
If a 58 mm condom remains uncomfortably restrictive, a 60 mm neighboring option may be worth comparing where the manufacturer offers one.
If 58 mm already feels loose, moving wider is unlikely to improve retention.
Moving from 58 mm to 62 mm is a larger change than moving from 58 mm to 60 mm.
The nominal-width difference is four millimetres.
58 mm equals approximately 2.28 inches flat, while 62 mm equals approximately 2.44 inches.
In doubled flat geometry, the difference increases from 116 mm to 124 mm.
That makes 62 mm a meaningfully wider product reference rather than merely another name for 58 mm.

The 58 mm number travels straight across the flattened condom from side to side. It does not wrap around the body.
A condom is flattened before nominal width is measured. The resulting number helps compare product dimensions.
There is no single body-girth measurement that universally requires every 58 mm condom.
The reason is that nominal width describes the condom itself, while fit depends on several factors:
If you are starting with your own circumference measurement, use our Condom Fit Chart by Girth instead.
Yes. In Trojan's current sizing information, Magnum XL uses an approximately 58 mm base nominal width.
However, Magnum XL does not remain 58 mm through its entire body.
Trojan currently lists it at approximately:
This is a good example of why saying “58 mm condom” may not completely describe a shaped product.
The 58 mm number describes the base, while the condom opens wider through the middle.

Yes.
Even when two condoms list the same 58 mm nominal width, they can differ in ways that affect real-world fit.
One condom may be straight while another may flare wider above the base.
Latex, polyurethane and other materials can stretch and conform differently.
Two products with 58 mm width can still have significantly different overall lengths.
Thickness can change feel even when the technical width is similar.
This is why nominal width is extremely useful for comparison but should not be treated as the only condom specification that matters.
If you are comparing 58 mm with another width, measure your body first rather than relying on appearance or assumptions.

A condom should fit securely, but a painfully restrictive fit is not the goal.
If a 58 mm product consistently feels excessively tight, compare the manufacturer's 60 mm, 62 mm or another suitable wider option where available.
Shape can also be responsible, so switching to a differently contoured product may help even without a large width change.
A wider condom still needs to remain securely positioned.
If 58 mm already feels loose, choosing a 60 mm or 62 mm product because it is marketed as XL is unlikely to improve fit.
A 58 mm condom is generally wider than many products marketed as regular or standard fit.
For example, some regular products sit around 53–56 mm depending on the brand.
Compared with a 53 mm condom, 58 mm is five millimetres wider across its flat nominal width.
Compared with 56 mm, it is two millimetres wider.
Those differences may sound small, but width changes occur across the entire condom and can be noticeable when the current product sits close to a fit boundary.
| Width | Difference From 58 mm | Flat Inches | Broad Comparison |
|---|---|---|---|
| 53 mm | 5 mm narrower | 2.09" | Standard example |
| 54 mm | 4 mm narrower | 2.13" | Regular example |
| 56 mm | 2 mm narrower | 2.20" | Regular / roomier |
| 57 mm | 1 mm narrower | 2.24" | Wide example |
| 58 mm | Reference | 2.28" | Large / wide |
Not necessarily.
XXL is a marketing label rather than a universal measurement standard.
One company could use an XXL label for a condom around 58–60 mm, while another manufacturer might reserve XXL for 64 mm or wider.
The same issue applies to terms such as:
The safest comparison is to look for the actual nominal-width number in millimetres.
Read XXL Condom Size for more detail.
Not automatically.
Width and length are different product measurements.
One 58 mm condom could be 180 mm long, while another 58 mm product could have a different length.
This matters because wider girth does not automatically mean someone requires the longest available condom.
When comparing 58 mm products, also check:
| Measurement | Millimetres | Centimetres | Inches |
|---|---|---|---|
| Nominal Width | 58 mm | 5.8 cm | 2.28" |
| Doubled Flat Width | 116 mm | 11.6 cm | 4.57" |
| 2 mm Narrower | 56 mm | 5.6 cm | 2.20" |
| 2 mm Wider | 60 mm | 6.0 cm | 2.36" |
| 4 mm Wider | 62 mm | 6.2 cm | 2.44" |
58 mm normally refers to condom nominal width, not body circumference.
Nominal width is measured across a flattened condom, not across the penis.
XL labels vary from one manufacturer and product family to another.
A 58 mm straight condom and 58 mm flared base can provide different body room.
Knowing width does not tell you the full condom length.
A condom that becomes too loose can shift or slip during use.
