UK Condom Sizes • Nominal Width • Inches / CM / MM
Use this Condom Size Chart UK to compare erect penis girth with condom nominal width, convert inches and centimetres into millimetres, and understand UK labels such as close, regular, wide, large and XL. Current Durex UK and Trojan UK examples are included so you can compare actual millimetres instead of relying only on marketing names.
Find a broad width range from girth, interpret a UK product width, compare two widths or check girth and product length together.
Enter erect girth and see the broad UK nominal-width comparison range used on this site.
Enter the millimetre width printed on a condom pack and see where it sits on this UK comparison chart.
Compare two products by actual millimetres instead of regular, large or XL labels.
Compare girth with product width and erect length with condom length in one result.
In the UK, condom packs commonly describe size using nominal width in millimetres. Nominal width is the condom measured flat from one side to the other. It is not penis girth, diameter or circumference.
| Erect Girth | Girth In Inches | Broad Nominal Width | Broad UK Fit Family |
|---|---|---|---|
| Below 110 mm | Below 4.33 in | 47–49 mm | Very close / snug |
| 110–119.9 mm | 4.33–4.72 in | 49–52 mm | Close fit |
| 120–129.9 mm | 4.72–5.11 in | 52–56 mm | Regular / balanced |
| 130–139.9 mm | 5.12–5.51 in | 56–60 mm | Wide / large |
| 140+ mm | 5.51+ in | 60–64+ mm | XL / extra wide |
Use nominal width to compare products across brands. Package labels can overlap, but millimetres are much easier to compare.
| Nominal Width | Inches | Broad Category | UK Shopping Context |
|---|---|---|---|
| 47 mm | 1.850 in | Very close / snug | Specialist narrow fit |
| 49 mm | 1.929 in | Close fit | Narrower than most mainstream regular sizes |
| 52 mm | 2.047 in | Close-to-regular | Common bridge width |
| 53 mm | 2.087 in | Regular / standard | Current Trojan straight standard examples |
| 54 mm | 2.126 in | Regular | Middle reference width |
| 56 mm | 2.205 in | Upper regular | Current Durex UK regular reference |
| 57 mm | 2.244 in | Wide | Current Durex UK wide reference |
| 60 mm | 2.362 in | Wide / XL transition | Large/wide territory |
| 64 mm | 2.520 in | Extra wide / XL | Specialist wide-fit territory |
Current Durex UK guidance gives clear reference points. Its buying guide states regular fit = 56 mm nominal width and wide fit = 57 mm nominal width. Durex's FitFinder asks users to measure around the widest part of the erection and describes the result as a recommendation.
Current Durex Nude Regular and Durex Intensity are 56 mm examples. Durex Originals Wide Fit is currently listed at 57 mm.
| Durex UK Fit | Current Width Reference | Example Context |
|---|---|---|
| Close Fit | Product-specific; current close examples around 52.5 mm | Closer fit |
| Regular Fit | 56 mm | Nude Regular / Intensity |
| Wide Fit | 57 mm buying-guide reference | Originals Wide Fit |
Trojan UK's current size chart separates base nominal width from mid-body flat width. Straight products keep the same width, while flared or bulbous condoms become wider through the shaft.
| Trojan UK Product | Base Width | Mid-Body Width | Shape Context |
|---|---|---|---|
| Ultra Thin | 53 mm | 53 mm | Straight |
| BareSkin | 53 mm | 53 mm | Straight |
| G.Spot | 53 mm | 54 mm | Contoured / bulbous |
| Ecstasy Ultra Ribbed | 53 mm | 73 mm | Very bulbous body |
Do not describe the Ecstasy example as a “73 mm condom” without context: its base is 53 mm and the larger number describes the body section.
This UK-focused figure maps broad girth bands onto nearby condom widths and overlays current Durex and Trojan UK reference points.
Measure while fully erect. Wrap a flexible tape around the widest part of the erection and record the full circumference. Keep the tape against the skin without compressing tissue.
If you only have string, use non-stretch string, mark the overlap and measure it against a ruler. Durex UK's current FitFinder uses the same widest-part approach.
Nominal width is the condom measured flat from edge to edge. A 56 mm condom does not mean the penis should measure 56 mm around. Penis girth is circumference; nominal width is a flat product dimension.
Because condoms stretch in use, there is no simple equal-value conversion between the two measurements.
Many UK users measure body girth in inches. Multiply inches by 25.4 to convert to millimetres.
| Erect Girth | Millimetres | Broad Width | Broad UK Category |
|---|---|---|---|
| 4.00 in | 101.60 mm | 47–49 mm | Snug |
| 4.25 in | 107.95 mm | 47–49 mm | Snug / close |
| 4.50 in | 114.30 mm | 49–52 mm | Close |
| 4.75 in | 120.65 mm | 52–56 mm | Regular |
| 5.00 in | 127.00 mm | 52–56 mm | Regular |
| 5.25 in | 133.35 mm | 56–60 mm | Wide / large |
| 5.50 in | 139.70 mm | 56–60 / compare 60+ mm | Wide / XL boundary |
| 5.75 in | 146.05 mm | 60–64+ mm | XL |
| 6.00 in | 152.40 mm | 60–64+ mm | Extra wide |
To convert centimetres to millimetres, multiply by 10. A 12.5 cm girth is 125 mm and a 13.5 cm girth is 135 mm.
| Girth | Millimetres | Broad Width | Broad Fit |
|---|---|---|---|
| 10.0 cm | 100 mm | 47–49 mm | Snug |
| 11.0 cm | 110 mm | 49–52 mm | Close |
| 12.0 cm | 120 mm | 52–56 mm | Regular boundary |
| 12.5 cm | 125 mm | 52–56 mm | Regular |
| 13.0 cm | 130 mm | 56–60 mm | Wide boundary |
| 13.5 cm | 135 mm | 56–60 mm | Wide / large |
| 14.0 cm | 140 mm | 60–64+ mm | XL boundary |
| 15.0 cm | 150 mm | 60–64+ mm | Extra wide |
There is no single legal UK millimetre definition of “regular”. On this site, regular is a broad 52–56 mm comparison zone. Current Durex UK places regular fit at 56 mm, while current Trojan UK straight standard examples sit at 53 mm.
Both are mainstream products, which shows why the actual nominal width is more useful than the label.
Large, wide and XL are marketing categories rather than universal technical standards. Broadly, 56–60 mm sits in wide/large territory here, while 60–64+ mm moves into XL or extra-wide territory.
Some large condoms use a wide base; others use a narrower base and a roomier body.
This chart treats 47–52 mm as the broad close side of the spectrum, with 47–49 mm especially narrow. Snug products can be useful when mainstream condoms repeatedly slip despite correct use.
4.5 inches equals about 114.3 mm. The broad starting range here is 49–52 mm nominal width. If a 52–53 mm product already feels secure and comfortable, there is no reason to downsize only because of a chart.
Five inches equals 127 mm and sits in the broad 52–56 mm regular band. Current Durex UK regular 56 mm is a relevant example, while Trojan's 53 mm standard products sit toward the closer side of the same broad area.
5.25 inches equals about 133.35 mm. This sits in the broad 56–60 mm wide/large band. Products around 56, 57 and 60 mm become logical comparisons depending on shape and manufacturer guidance.
5.5 inches equals about 139.7 mm, close to the transition from 56–60 mm wide sizing into 60+ mm extra-wide sizing. Boundary measurements are a good reason to compare nearby sizes instead of treating one cut-off as absolute.
Six inches equals 152.4 mm and sits clearly in extra-wide territory on this chart. Compare manufacturer-specific XL or custom-fit products rather than forcing a mainstream regular width.
52 mm is about 2.047 inches flat width and sits near the close-to-regular transition. It can be useful when 53–56 mm products feel slightly roomy or when girth sits at the lower end of the regular range.
53 mm equals about 2.087 inches flat width. Current Trojan UK Ultra Thin and BareSkin are 53 mm at both base and mid-body, making this a useful current standard-width reference.
54 mm equals about 2.126 inches and sits in the middle of this site's regular range. It is a useful comparison point between 52–53 mm closer products and 56 mm upper-regular products.
56 mm equals about 2.205 inches. Current Durex UK guidance identifies 56 mm as regular fit. Durex Nude Regular and Durex Intensity are current 56 mm examples.
57 mm equals about 2.244 inches. Current Durex UK guidance identifies 57 mm as wide fit, and Durex Originals Wide Fit is a current 57 mm example.
60 mm equals about 2.362 inches and sits at the upper end of wide sizing and lower edge of XL territory here. Moving from 56 to 60 mm is a meaningful 4 mm increase in flat width.
64 mm equals about 2.520 inches and belongs to specialist extra-wide / XL territory. It is most relevant when mainstream 56–60 mm products remain clearly restrictive.
A condom labelled regular by one manufacturer can be wider or narrower than a regular condom from another. The same applies to large, wide, XL, close and snug.
Use package wording inside one brand, but use actual millimetres when comparing across brands.
Most simple charts show one nominal width, but shaped condoms can need more detail. Trojan UK's chart lists base and mid-body widths separately, showing how a condom can stay secure at the base while adding room through the shaft or head.
Painful pressure, numbness, strong constriction or major difficulty unrolling despite correct orientation are reasons to compare a wider nominal width or different shape. Tightest is not automatically safest.
Repeated slipping, coming off or excessive looseness can indicate that the base width is too large. Check correct application first, then compare a narrower base if the problem continues.
NHS guidance tells UK users to check the packet for a European CE mark or UKCA mark and to check that the use-by date has not expired. UK government medical-device guidance also identifies condoms as medical devices.
Conformity marking does not replace correct use: follow the manufacturer's instructions and inspect the packet before opening.
When shopping online, check that the seller clearly identifies the manufacturer, product size and material. Look for nominal width rather than relying only on words such as regular or XL.
If a listing gives conflicting dimensions, verify the technical specification on the manufacturer's official UK page.
Width and length should be treated separately. A condom can be regular width and long, or wide and comparatively short. Current Durex Nude Regular is 56 mm nominal width and 195 mm length; current Trojan Ultra Thin is around 170–190 mm long with a 53 mm base.
| Product Length | Approx. Inches | General Interpretation |
|---|---|---|
| 170 mm | 6.69 in | Shorter mainstream length |
| 180 mm | 7.09 in | Common middle length |
| 190 mm | 7.48 in | Common long mainstream length |
| 195 mm | 7.68 in | Current Durex Nude Regular example |
| 200+ mm | 7.87+ in | Long / XL territory |
A 49 mm condom is about 1.929 inches wide when laid flat and sits in close-fit territory. It is most useful for people who find typical 53–56 mm mainstream products too loose or prone to slipping.
On this site's broad chart, 49 mm is most relevant around the lower-girth end of the spectrum, especially below roughly 120 mm erect circumference. Brand-specific fit charts should still be checked because product stretch and shape can change how a 49 mm condom feels.
51 mm is about 2.008 inches flat width. It sits between 49 mm close-fit products and 52–53 mm regular-transition products, so it can be useful when one size feels too snug and the next common mainstream width feels too roomy.
Because 51 mm is less common in mainstream UK supermarket ranges, specialist or custom-fit brands may be easier places to find it.
58 mm is about 2.283 inches flat width and belongs in the wide / large part of this chart. It is a useful intermediate width between current Durex UK's 57 mm wide reference and 60 mm extra-wide transition products.
If 57 mm still feels clearly restrictive but 60 mm feels unnecessarily roomy, 58 mm can be a sensible technical comparison where available.
62 mm is about 2.441 inches flat width and sits inside extra-wide / XL territory. It is not a common mainstream UK reference width, but shaped large condoms can reach similar body widths even when their base is narrower.
This is why you should distinguish a true 62 mm nominal/base condom from a flared product that only widens to around 62 mm through the shaft.
The difference between regular and wide can be surprisingly small in one brand and much larger in another. Durex UK's current buying guide places regular at 56 mm and wide at 57 mm, only a 1 mm flat-width difference.
Other products marketed as wide may use 60 mm or more. The label tells you the product's position inside that brand, but the millimetre specification tells you how it compares technically with another brand.
On this site, 56–60 mm is the broad wide/large zone and 60–64+ mm is XL / extra-wide territory. The 60 mm point is therefore a transition rather than a universal boundary.
If you are near 140 mm girth, comparing 57, 60, 62 and 64 mm products can be more useful than assuming the word XL automatically means one specific width.
A straight condom keeps a similar width from base through much of the shaft. A flared, tapered or bulbous condom can use a relatively moderate base and then add room higher up.
Trojan UK's current chart demonstrates this clearly: its straight Ultra Thin and BareSkin examples remain 53 mm at the base and mid-body, while its shaped products can become much wider through the body. Therefore one number may not describe the whole fit of a shaped condom.
Natural rubber latex, polyurethane, polyisoprene and nitrile do not all stretch and drape in exactly the same way. Two condoms with the same nominal width can therefore feel different.
If you switch from latex to a latex-free material, use your familiar width as a starting comparison rather than assuming the same millimetre number will feel identical. Fit should still be confirmed by security and comfort.
Shorter length does not automatically mean a narrow condom. A shorter penis can still have a wide girth and need a 56–60 mm or wider product.
If the width is correct but too much condom remains rolled or bunches at the base, compare a shorter product at the same or similar nominal width. Do not reduce width simply to solve a length issue.
A longer penis does not automatically need a wide condom. Someone can need a long 52–54 mm product, a long 56 mm product or a long 60 mm product depending on girth.
Check product length separately from nominal width. Long and wide are different dimensions even when brands package both under an XL label.
Boundary measurements are common. If you repeatedly measure around 119–121 mm, 129–131 mm or 139–141 mm, do not treat one millimetre as a hard dividing line.
Compare nearby widths on both sides of the boundary, starting with the brand's own fit chart. Product material, shape and desired tension can make either neighbouring width reasonable.
One millimetre sounds small, but nominal width is measured flat. A 1 mm increase corresponds to roughly 2 mm more simple flat perimeter before stretch.
Near a fit boundary, that can be noticeable. This is why Durex's 56 mm regular and 57 mm wide products can feel different even though the numerical step is small.
A move from 52 to 56 mm, or from 56 to 60 mm, is a substantial size change. Four millimetres of flat width corresponds to about 8 mm more simple flat perimeter before stretch.
Large jumps make most sense when the current condom is clearly too tight or too loose. If the fit problem is mild, compare intermediate widths first.
Yes. Equal nominal width does not guarantee identical fit because length, shape, material, lubrication and manufacturing design can differ.
Use the width as the first technical comparison, then use real-world fit to decide between products that share the same number.
A general chart is useful for understanding the landscape and narrowing your options. A brand calculator or official size guide is better for choosing within one manufacturer's product system.
The best workflow is: measure girth, use a broad chart to identify nearby widths, then use the exact Durex, Trojan or other brand guidance for the product you plan to buy.
Two users with the same girth may prefer slightly different nearby widths. One may prefer more base grip, while another may prefer more room through the shaft.
Preference is reasonable as long as the condom remains secure, does not repeatedly slip and does not create painful constriction. Fit charts should guide the comparison rather than force one single answer.
| Your Situation | What To Compare | Why |
|---|---|---|
| Secure and comfortable | Stay near current dimensions | No obvious fit problem |
| Painfully tight | Wider nominal width | Current width may be too narrow |
| Repeated slipping | Narrower base width | Current base may be too wide |
| Base secure, head cramped | Flared or bulbous product | Add upper-body room |
| Does not reach base | Longer condom | Length issue |
| Too much rolled material | Shorter product at similar width | Length issue, not necessarily width |
NHS guidance advises using a new condom every time, following the packet instructions, checking the use-by date and checking for a CE or UKCA mark.
Do not use more than one condom at the same time. With latex condoms, use water-based or silicone-based lubricant rather than oil-based products that can weaken latex.
