Compare Widths • Match Nearby Sizes • Understand Shape
Compare MyONE vs Trojan condom sizes using published dimensions instead of trying to match marketing labels. MyONE uses a granular custom-fit system with multiple width and length combinations, while Trojan uses model-specific dimensions that can include base width, mid-body width, length and shape. Use the tools below to find the closest technical comparison.
Match width families, compare Trojan base and mid-body geometry, review model profiles and keep body girth separate from product dimensions.
Select a current MyONE width family. The tool finds nearby Trojan base widths, then reminds you where Trojan's mid-body geometry changes the comparison.
Choose a Trojan model and find the nearest MyONE width families by Trojan base width. Mid-body shape remains a separate factor.
Review a Trojan model's base width, mid-body width, length range and shape before comparing it with a MyONE width family.
Enter erect girth and choose a MyONE or Trojan width reference. The result keeps body circumference and flat product width separate.
MyONE and Trojan solve condom fit in very different ways. MyONE's current custom-fit product pages state that its system uses 10 lengths and 9 widths. Current MyONE US product/collection pages show width families including 45, 47, 49, 51, 53, 55, 57, 60 and 64 mm. Each width can be paired with multiple length codes, creating many more combinations than a simple small/regular/large range.
Trojan's official size chart is organised by product model. Many standard Trojan condoms use a 53 mm base width, but some shaped models become much wider through the mid-body. Magnum models span several base widths and shapes: Magnum Original and Thin currently list 55 mm base / 62 mm mid-body, Magnum Raw and BareSkin 57 / 60 mm, Magnum XL 58 / 63 mm, and Magnum Ecstasy 53 / 73 mm.
The result is that there is no single “Trojan size” that equals one MyONE code. The closest comparison starts with base width, then checks mid-body shape, length and material.
| Width / Model | MyONE System | Trojan Example | Shape / Length Note | Cross-Brand Interpretation |
|---|---|---|---|---|
| 45 mm | MyONE 45 width family | No equivalent Trojan base width in current main chart | MyONE pairs width with multiple lengths | MyONE offers much narrower options. |
| 47 mm | MyONE 47 width family | No direct current Trojan base match | Custom-fit option | Narrower than Trojan's common 53 mm base. |
| 49 mm | MyONE 49 width family | No direct current Trojan base match | Custom-fit option | 4 mm narrower than common Trojan 53 mm base. |
| 51 mm | MyONE 51 width family | Closest common Trojan base: 53 mm | Trojan Original is straight | Trojan is 2 mm wider at base. |
| 53 mm | MyONE 53 width family | Trojan Original / Ultra Thin / BareSkin and several others: 53 mm base | Trojan shapes vary by model | Exact base-width match for several models. |
| 55 mm | MyONE 55 width family | Ultra Fit Comfort Feel / Magnum Original / Thin / Ribbed: 55 mm base | Often widens to 62 mm | Base can match exactly while mid-body differs. |
| 57 mm | MyONE 57 width family | Magnum Raw / BareSkin: 57 mm base | Trojan widens to 60 mm | Exact base match, different contour. |
| 60 mm | MyONE 60 width family | No current Trojan model uses 60 mm base in main chart | 60 mm appears as mid-body on Magnum Raw/BareSkin | Do not compare MyONE 60 base with Trojan 60 mid-body as identical. |
| 64 mm | MyONE 64 width family | No 64 mm Trojan base in current main chart | Trojan Magnum XL mid-body is 63 mm | Similar number can describe a different location on the product. |
MyONE is built around a custom-fit concept rather than a few broad labels. Current official product pages describe a system with 10 lengths and 9 widths. The width portion of a current MyONE size code is visible directly in codes such as 47F, 55G, 57F, 60F or 64F. The number identifies the width family, while the letter identifies a length category.
MyONE's current collection pages show width families at 45, 47, 49, 51, 53, 55, 57, 60 and 64 mm in the US system. MyONE also maintains a separate page stating that 69 mm condoms are sold in the UK and EU, while US availability has historically been constrained by regulation. Because regional ranges can differ, a MyONE size comparison should always specify the market being discussed.
The practical advantage of MyONE is dimensional granularity. If a standard condom feels correct in width but has substantial excess length—or the opposite—MyONE can pair the same width with a different length family. That makes a MyONE code more specific than a one-word size such as regular or large.
MyONE's measuring instructions tell users to measure while erect, measure length along the top, and wrap the tape gently around the thickest part for girth. Its fit system then converts those body measurements into a FitCode.

Trojan's system is product-model based. Its current official size chart lists a length range, a base nominal/flat width and, where relevant, a different mid-body flat width. This is particularly important for contoured models because a condom can be snug at the base and much roomier higher up.
Many classic Trojan models—including Original, Ultra Thin and BareSkin—currently use a 53 mm base and 53 mm mid-body width. Others keep the same 53 mm base while opening much wider through the body. Trojan Her Pleasure Sensations and some Ultra Fit profiles currently list a 53 mm base with a 63 mm mid-body, while certain Ecstasy models list a 53 mm base and 73 mm mid-body.
Magnum products move into larger or more contoured profiles. Magnum Original, Thin and Ribbed list 55 mm base / 62 mm mid-body. Magnum Raw and Magnum BareSkin list 57 / 60 mm. Magnum XL lists 58 / 63 mm. Magnum Ecstasy is unusual because its base is 53 mm but its mid-body expands to 73 mm.
This means the word “Magnum” alone is not a width. Different Magnum models have different base, mid-body and length dimensions.

This is one of the cleanest numerical comparisons. MyONE has a 53 mm width family, and Trojan Original currently lists 53 mm at both the base and mid-body. At the flat-width level, the two therefore share the same 53 mm reference.
That does not make them identical. MyONE can pair 53 mm with multiple length categories, while Trojan Original currently lists a 170–190 mm product length range and a straight shape. Material formula, wall thickness, lubrication and ring construction can also differ.
If your current MyONE 53 fits well around the shaft and you want to try Trojan Original, 53 mm is a reasonable technical starting point for width comparison. Preserve your MyONE length code because Trojan's fixed product length may create a different amount of rolled or excess material.
MyONE's 55 mm width family matches the 55 mm base width of Trojan Magnum Original, Magnum Thin and Magnum Ribbed. At the base, that is an exact numerical match. Through the body, however, those Magnum models widen to 62 mm and use a tapered/flared shape.
A MyONE 55 product should therefore not be described as “the same size as Magnum Original” without qualification. The base width matches, but Magnum becomes 7 mm wider through its mid-body. Depending on body shape and preference, that extra room may be noticeable.
Magnum Original currently lists a length range of 180–200 mm. MyONE's 55 family can be paired with multiple lengths, so the closest MyONE equivalent would depend on both width and the letter/length portion of the user's FitCode.
MyONE 57 mm aligns numerically with the current 57 mm base width of Trojan Magnum Raw and Magnum BareSkin. Those Trojan models currently widen to 60 mm through the mid-body and use a tapered/flared shape.
If a MyONE 57 width fits securely, Magnum Raw or BareSkin can be considered nearby base-width candidates, but expect a different shape. The Trojan products offer approximately 3 mm more flat room through the wider part of the body than at the base.
Magnum Raw currently lists 190–210 mm length, so MyONE users should also compare their current FitCode length before switching.
MyONE 60 is a 60 mm width family. In Trojan's current Magnum chart, 60 mm appears as a mid-body width on Magnum Raw and Magnum BareSkin, but their base width is 57 mm. This is a classic example of why one number cannot be compared without knowing where it is measured.
A MyONE 60 product is not automatically equivalent to Magnum Raw simply because both tables contain the number 60. If MyONE 60 describes the nominal/base width family while Trojan 60 describes the wider mid-body portion, the base tension can be different.
Someone moving from MyONE 60 to Trojan should compare the Trojan base width first. Among current Magnum models, Magnum XL has the widest listed base in the main chart at 58 mm, still 2 mm narrower than a MyONE 60 width family at the base.
MyONE's current US system includes a 64 mm width family. Trojan Magnum XL currently lists a 58 mm base and 63 mm mid-body. The 63 mm mid-body is numerically close to MyONE 64, but again the measurement location is different.
At the base, Magnum XL is 6 mm narrower than a MyONE 64 width family. Through the wider body, it reaches 63 mm, only 1 mm below 64 mm. That tapered shape may feel secure at the base while providing more room higher up, which is fundamentally different from assuming a uniform 64 mm product.
If a user specifically needs a very wide base rather than only a roomier mid-body, MyONE's larger width families may offer a closer technical match than Trojan's contoured models.
MyONE starts with width + length combinations; Trojan often starts with a fixed model shape containing base and mid-body dimensions.
Example: 53F preserves a 53 mm width family plus a separate length category.
Example: Magnum Original is 55 mm at the base and 62 mm through the wider body.
A 60 mm MyONE width and a 60 mm Trojan mid-body are not automatically the same fit.
The key structural difference is range coverage. MyONE extends substantially narrower than Trojan's common standard base width, offering current US width families at 45, 47, 49 and 51 mm before reaching 53 mm. Trojan's standard latex range is concentrated around a 53 mm base, with selected larger models moving to 55, 57 or 58 mm at the base.
At the wider end, MyONE continues to 60 and 64 mm base-width families. Trojan's larger products often create room by flaring above a narrower base rather than simply using a uniformly wider base. That means users who need a very narrow or very wide base may find MyONE offers more granular base-width choices.
A Trojan Original-style 53 mm straight model sits directly between MyONE's 51, 53 and 55 width families. MyONE 53 is the exact numerical base-width match. MyONE 51 is 2 mm narrower, while MyONE 55 is 2 mm wider.
This creates a useful troubleshooting ladder. If a Trojan 53 mm straight condom feels slightly loose, a MyONE 51 width family could be a nearby narrower comparison. If it feels noticeably tight, MyONE 55 gives a nearby wider comparison. The correct MyONE length code still needs to be selected separately.
Do not treat this as a guaranteed fit recommendation. Material and construction differ, and real fit should remain secure without painful constriction.
Magnum condoms show why shape matters. Magnum Original uses a 55 mm base but expands to 62 mm through the mid-body. Magnum Raw uses 57 mm at the base and 60 mm through the body. Magnum XL uses 58 / 63 mm. Magnum Ecstasy uses a 53 mm base but expands dramatically to 73 mm.
MyONE width-family numbers are more useful as a base-width comparison. If a person likes Magnum's tapered base and roomy upper profile, simply switching to a MyONE width equal to Magnum's widest point may create a much looser base than expected.
Conversely, a person who dislikes the wider upper room in a shaped Magnum may prefer a product with a more consistent width, even if the base dimensions are similar.
MyONE's major advantage is that width and length can be adjusted more independently. Current product pages state 10 lengths and 9 widths. A person can therefore remain in the same width family while changing the length code.
Trojan uses model-specific length ranges. Trojan Original is currently 170–190 mm, Magnum Original 180–200 mm, Magnum Raw 190–210 mm and Magnum XL 180–200 mm. Choosing a different Trojan model can therefore change width, shape and length at the same time.
If your width fit is good but length is the problem, a MyONE custom-length option can make comparison easier because fewer variables need to change at once.
In purely dimensional terms, MyONE currently offers much narrower base-width families than the standard Trojan chart. MyONE's 45, 47, 49 and 51 mm families all sit below Trojan's common 53 mm standard base width.
That does not mean MyONE is automatically better for every user. If a 53 mm Trojan product already stays secure and comfortable, there may be no need to move narrower. The value of MyONE's narrower sizes appears when standard widths consistently slip or feel baggy despite correct use.
The answer depends on where you need more room. MyONE offers wider base-width families such as 57, 60 and 64 mm. Trojan Magnum often keeps a somewhat narrower base and creates extra room through a flared or bulbous body.
If your main problem is excessive base tightness, MyONE's wider base families may be more directly relevant. If you prefer a secure base but more room toward the head or mid-shaft, a contoured Magnum profile may suit that geometry better.
Neither approach is universally superior. The products solve different shape requirements.
Current MyONE custom-fit product pages describe Sensatex latex. Trojan's standard and Magnum ranges are predominantly premium latex, while Trojan also sells separate non-latex products such as Raw Pure Feel Non-Latex and Supra BareSkin in its broader chart.
Material matters because equal nominal widths can feel different depending on elasticity, wall construction and lubrication. Anyone with a latex allergy or sensitivity should verify the exact product material and use an appropriate non-latex option rather than choosing solely by width.
Start with the Trojan model's base width, not its widest mid-body number. Then select the nearest MyONE width family. Next, measure or record the Trojan length and choose a MyONE length category appropriate to your erect length using MyONE's FitCode system.
Do not use “Trojan” or “Magnum” as one generic size.

Record the number portion of your MyONE width family and the letter/length portion of your current FitCode. Search Trojan's current chart for a nearby base width, then examine the model's mid-body geometry and length range.
A MyONE 53 user can compare Trojan's many 53 mm base models, but should decide whether a straight 53/53 model or a contoured 53/63 or 53/73 profile is more appropriate. A MyONE 55 user can compare Magnum Original-style 55/62 models. A MyONE 57 user can compare Magnum Raw/BareSkin 57/60 models.
MyONE 60 and 64 users should be especially cautious: Trojan's similar larger numbers may describe the mid-body rather than the base.
Girth remains your body circumference regardless of brand. MyONE explicitly instructs users to wrap a tape gently around the thickest part of the erection. Trojan's large-condom guidance also uses length and girth context, but product selection is ultimately model-specific.
Do not compare a 115 mm body girth directly with a 55 mm condom width as if they should match numerically. Use a manufacturer sizing method or a clearly explained starting range. Our Girth to Condom Width page separates those dimensions.
For unit conversion, use Condom Girth Inches to mm. For width conversions, use Condom Size mm to Inches.
Cross-brand fit can change even when base width matches because shape, length, material and lubrication can differ. Confirm correct orientation and application before assuming every issue comes from width.
If “flexible” means the number of width-and-length combinations, MyONE's custom-fit system is more granular. The current MyONE pages state 10 lengths and 9 widths. Trojan offers fewer base-width increments but compensates with a broad model range and several distinct shapes, including straight, tapered/flared and super-bulbous profiles.
MyONE is therefore useful for fine-tuning base width and length independently, while Trojan provides many ready-made shape profiles. Which system works better depends on whether your fit issue is primarily width, length, contour or a combination.
