Understand the measurement
Learn what to measure and how to interpret common product dimensions.
Start here
What are you sizing?
Choose the product type closest to what you are shopping for.
One source of truth
How sizing works on CherryAffairs
Narrow the catalogue
Use grouped filters such as Wearable Fit and Insertable Length to reduce the choices.
Check the exact item
Review the actual variants, manufacturer measurements and size-chart image before ordering.
!
Do not choose from the filter label alone
Broad groups make browsing easier, but brands and product designs differ. The exact product page remains the final reference.
Lingerie & costumes
How to Measure for Lingerie and Costumes
Your normal clothing label is only a starting point. Measure yourself, then compare those measurements with the chart displayed inside the exact product’s specifications.
Measure around the fullest part while keeping the tape level.
Measure directly beneath the bust. This matters most for bras and structured tops.
Measure around the narrowest part of your torso without pulling the tape tight.
Measure below the natural waist where lower-rise garments sit.
Measure around the fullest part of your hips and seat.
Especially useful for bodysuits, costumes and garments with limited vertical stretch.
| Product type | Measurements to prioritise | Check on the product page |
|---|---|---|
| Bras and adhesive bras | Bust and underbust | Band, cup and regional-size conversion |
| Babydolls and chemises | Bust, then waist | Stretch, cup range and adjustable straps |
| Bodysuits and costumes | Bust, waist, hips and torso length | Garment cut and vertical stretch |
| Panties and briefs | Waist and hips | Rise and stretch |
| Bodystockings and hosiery | Hips, height and stretch | One-size range and material elasticity |
| Men’s underwear | Waist | Pouch design and brand-specific fit |
A combined range, not proof that the garment fits every body within both labels.
A manufacturer-defined measurement range. It does not mean universal fit.
A separate extended range. Always check the displayed chart.
Plus-size groupings that vary substantially between brands.
How the filter works
Wearable Fit is a broad discovery tool
It groups products according to the actual clothing sizes stored on each product. It does not replace the brand-specific chart shown on the product page.

Check the chart before ordering
Brand sizing varies, and intimate products are subject to hygiene restrictions. Compare your measurements with the exact chart shown on the product page, or contact us before ordering if the fit is unclear. Review the Returns & Warranty Policy for the current terms.
Insertable toys
How to Read Insertable Length, Width and Diameter
Compare insertable length together with width, maximum diameter, shape, taper and flexibility. Total length alone rarely tells the full story.
The full product from end to end, including handles, bases or controls.
The portion intended to enter the body. It may be shorter than the total length.
The straight distance across the product at the measured point.
The distance around the product. Approximate circumference equals diameter multiplied by 3.14.
The widest insertable point, which may matter more than average shaft width.
A gradual taper or flexible material can feel different from a blunt or firm design of the same dimensions.
How the filter works
Insertable Length uses documented body-insertable measurements
We normalize documented measurements to centimetres, then place them into these broad comparison ranges. This filter applies to the portion intended to enter the body. It does not represent masturbator canal depth, condom width or ring fit.
01Up to 8 cmCompact
02Over 8 to 12 cmShort
03Over 12 to 15 cmMedium
04Over 15 to 18 cmLong
05Over 18 to 22 cmExtra-long
06Over 22 cmVery long
Quick converter
Diameter and circumference
Use this only as an approximate conversion. Confirm the manufacturer’s exact specification.
Chart converter
Centimetres and inches
Useful when your body measurements and a supplier size chart use different units.
Important: These bands make products easier to compare. They are not experience-level or comfort guarantees.
Masturbators
How Masturbator Size and Canal Length Are Measured
Manufacturers may report overall length, internal depth or usable canal length. Read the product specifications before comparing two products.
Usable canal length
The internal depth available for use. This may be shorter than the external product body.
Opening and stretch
Opening width, sleeve elasticity and texture affect fit differently from length.
Open or closed end
Open-ended sleeves can accommodate length differently from closed-ended products.
Suction and pressure
Adjustable air, pressure or tightness can matter more than the outside dimensions.
i
How to compare masturbator fit
Compare usable canal length or internal depth in the product specifications. The Insertable Length filter does not represent masturbator sleeve depth, so confirm the manufacturer's wording before comparing models.
Rings & wearable toys
How to Size Rings, Harnesses and Wearable Toys
Clothing labels are not appropriate for every wearable product. Fixed rings, stretch rings, harnesses and wearable vibrators each use different fit information.
Inner diameter
Use the opening measurement, not the product’s outside width.
Material and maximum stretch
Check the manufacturer’s recommended fit range and do not assume every elastic material stretches equally.
Waist and thigh range
Look for minimum and maximum adjustable measurements.
Adjustability and placement
Check straps, magnets, garment compatibility and intended body placement.
Internal dimensions
Confirm internal length and diameter rather than relying on the overall product size.
Choose adjustable first
An adjustable design is usually easier to assess when your exact fit is uncertain.
Condoms
How Condom Nominal Width and Fit Work
Nominal width is the condom’s flat width. Different brands can use different marketing labels for similar measurements.
Nominal widthFlat width of the condom
It is not the same as diameter or circumference. Always check the exact package or product specification.
Common questions
Size and fit questions
Open a question for the practical answer.
我应该选择平时穿的服装尺码吗？
仅将其作为起点。请测量自己的尺寸，并将测量结果与具体产品页面上显示的尺码表进行比较。不同品牌的尺码可能存在很大差异。
“均码”是什么意思？
均码表示制造商根据注明的尺寸范围设计了该服装。这并不意味着适合所有人。请查看该产品页面上显示的尺码表。
如果我的服装尺码介于两个尺码之间，该怎么办？
优先考虑服装中弹性最小或结构最固定的部位，然后查看产品的材质、弹性和可调节设计。如果尺码表或版型不明确，请在订购前联系我们。
如何测量自己的内衣尺寸？
在胸围最丰满处、自然腰围最纤细处以及臀部最丰满处进行测量。部分胸罩还需要测量下胸围，而连体衣和服装可能需要测量躯干长度。将您的尺寸与具体商品页面上显示的尺码表进行比较。
总长度和可插入长度一样吗？
不。总长度包括整个产品。可插入长度是指设计用于进入身体的部分，可能不包括手柄、底座或控制部分。
宽度和直径相同吗？
有时是，但并非总是如此。直径表示圆形截面两端之间的直线距离。对于不规则形状或非圆形形状，制造商可能会使用“宽度”一词，因此请查看示意图或规格说明的具体语境。
初学者应选择多长的可插入长度？
不存在适用于所有人的通用新手尺寸。长度、最大直径、锥度、形状、柔韧性和预期用途都很重要。请使用筛选条件进行比较，但不要将其视为舒适度保证。
我该如何选择假阳具或振动棒的尺寸？
比较可插入长度、最大直径、形状、锥度和材料柔韧性。不要仅根据总长度进行选择，因为产品的一部分可能是手柄、底座或控制部分。
可插入长度显示在哪里？
打开产品页面并查看“规格”。制造商提供可插入尺寸时，会将其换算为厘米，并据此将产品归入“可插入长度”筛选区间。此筛选条件适用于可插入玩具，不适用于自慰器的通道深度。
男性自慰器的尺寸如何测量？
制造商可能会列出产品总长度、内部深度或可用导管长度。比较产品前，请查看产品规格中的确切表述。
我在哪里可以找到精确的内衣尺码表？
打开产品页面并展开“规格”。提供尺码表的产品会在此处显示品牌专属的尺码表图片。
如果尺码不合适，我可以退货吗？
私密产品受卫生限制。下单前请查看退货与保修政策，如果尺寸信息不明确，请在购买前联系我们。
