Strap ons come in a range of sizes from under 5 inches and can range up to between 9 and 10 inches. Circumference sizes range from beginners at around 4 inches, up to larger sizes of between 5.5 inches and 7 inches (or above). So knowing the size of the strap-on to get is critical for safe, comfortable and pleasurable use. Thus, we preprared the following strap-on sizing guide where we disucss how to measure yourself and your partner for a most fitting strap-on toy!
How to Measure for a Strap-On?
To measure a vagina, you will need a vibrator (if possible), or an alternative object which is long, clean and has a smooth surface. To begin, either you or your partner lay on their back with legs spread. The vagina needs stimulating at this point, as it elongates when it is aroused. Once aroused, you can start sliding the vibrator or phallic object into the vagina. When you reach the max comfortable depth, mark this on the vibrator/phallic object. This is the strap on length (for the dildo or vibrator) which the vagina can safely handle.
To measure circumference or girth, you can use your fingers and slide one at a time until you reach the limit. Then, wrap the tape measure around the fingers and you;ll get the circumference of the strap-on the vagina can comfortably take..
Sex Toy Measurements
Generally speaking there are four vital measurements for any sex toy you need to know:
Length: The full length of the toy from the two farthest points, which we refer to as total lenght.
Insertable Length: The length of the toy that can be safely inserted.
Width (or diameter): The distance between the two sides of the toy.
Girth (or circumference): The circumference of the toy which is relevant to insertable toys.
Sizing for Hollow Strap-Ons
A hollow strap-on is mostly worn by men who have a smaller penis, so for these, measure the length f the penis when it is fully aroused (if possible). It is the measurement that ensures the penis will fit in the hollow dildo canal.This is to make sure they can fit their penis inside the hollow canal.
Make sure you measure the circumference and calculate the diameter, as most product descriptions share the diameter of the hollow dildo strap-on. It is a simple math - divide the circumference by 3.14 and you'll get the diameter, and you'll know the size to look for.

Sizing for Vibrating Strap-Ons
You need to measure the length and circumference of the vibrating strap-on. If you get a simpler vibrating strap-on with a dildo and an harness, then only measure the safe size the receiver can manage. But if you are looking to buy a strapless strap-on, then you should also know the size the wearer can manage.
To measure for a strapless strap-on, you need to measure the size the vagina can safely take, as the strapless strap-on is worn in the vagina and held in place by the Kegel muscles. If you have previous experience with egg vibes, these can be a good starting point. However, if you don't have a previous reference, then use deduction to find a model that will be comfortable. Even better, you can get an inflatable strapless strap-on for a perfect fit.

Sizing for Strap-On Compatible Dildos
Strap-on or harness compatible dildos are designed to give a unique feel to the receiver. They come in varying ranges, so you can get a small, medium, and even large strap-on compatible dildos. To measure the insertable length, you can us ethe method we described above: measure the length the vagina can safely take when it is fully aroused. Do this with a dildo, a vibrator or another phallic object and you'll get the length of the dildo. While you are at it, measure the circumference and calculate the diameter, and you'll get a good idea of the size of strap-on compatible dildo to get.
You can find insertable lengths of strap-on compatible dildos at around 5 to 6 inches and then larger varieties of between 7 to 8 inches. Please note that to fit the dildo in the strap-on, you need to take into account the O-ring and base, as once fitted in the harness, the insertable lenght gets shorter. In any case, our product descriptions tend to share the insertable length for most strap-on compatible dildos, so we have you covered.

Sizing for Strap-On Harness
To measure for a strap-on harness is much easier than measuring for the accompanying toy. Becasue most strap-on harnessses are adjustable, you can look at the general product description where we share the range of adjustability, so you will know your chosen model will be the right ft.
Measure you waist for the main waist size; then measure around your thighs where the harness will fit. For this, we recommend you use a flexible tape measure that will allow you to wrap it around your thighs and butt, measuring the exact size you need. Also, note that most adjustable strap-on harnesses have a give of about 5-10 inches, so you can safely get a model that appeals to you visually and you can expect it will fit you nicely.
If you are going after a strap-on underwear model, then you need to be more careful, as these are not adjustable. Our product descriptions list the sizes for each strap-on underwear model, which are comparable to the US dress sizes, so you can find the one that is closest to your size. We also have a plus-size strap-on harnesses and underwear category for those ladies with broader hips.

How to Choose the Best Strap-On Dildo Harness
As you’ve seen above, you have so many strap-on harness options. Choosing a strap-on harness depends on your preference, intended use, and skill level. Here are some tips that can help you hone in on what model would be best for you.
If you want some light fun, you can opt for an underwear-style harness that comes with visual appeal and is effortless to maintain.
If you are into serious roleplay and want to take the male role, then we suggest you pick a strap-on harness model that provides better control, like a double-strap harness.
Strap-On Harness Considerations
The size of the harness is essential, as you need a harness that fits snugly on your body. If the harness is loose, then you risk losing control and ruining the experience. If your harness is too tight, you will be uncomfortable and even risk restricting circulation. Make sure your harness fits comfortably, as you don’t want it bumping on the vaginal mound too much, which can lead to desensitizing of the area and diminished sensitivity.
The next thing to consider is the material of the harness, as you are wearing this on your bare skin. The material should be body-safe and comfortable, so we advise you opt for woven nylon, leather, silicone, rubber, or faux leather strap-on harness materials for harnesses with straps and microfiber for underwear strap-on harnesses.
If you find that you can’t stand the feeling of the harness material on your body, you can put on a pair of underwear underneath the strap-on harness. Also, make sure you play gently, as too vigorous movements can make the strap-on harness loose, and you risk harming your partner.
Strap-On Harness Benefits
You get a lot of benefits from introducing a strap-on in your sexy games. These are designed to accommodate a strap-on dildo with which you can penetrate your partner. But if you want solo playtime, you can try the arm or thigh harnesses and attach them to various furniture.
All the different strap-on harnesses have their appeal, as some are for beginners, some are very sexy, and some are very versatile. Still, the double-strap harness is the most versatile model, as it is very adjustable, stays in place, and holds the dildo securely. Using a quality double-strap harness will allow you to concentrate on pleasuring your partner instead of worrying that the dildo will slip away.
Some of the aforementioned strap-on harnesses can be worn by men, which opens up a new avenue for sexy play. Some are designed for double penetration of a female partner. In contrast, others come with hollow dildo attachments that help men with ED or premature ejaculation or add length and girth to the man’s penis.

Strap-On Safety Considerations
Always take caution when putting your strap-on harness on, as you can overtighten the straps if you are not careful. Please note that reputable manufacturers have safety measures in place to protect users against this, which is why there are harnesses in different sizes. Make sure you get the correct size strap-on harness to start with.
Another thing to consider is the O-ring buckles, as these are usually metal snaps that hold the O-ring in place. When you get your strap-on harness, make sure you check for any rough edges that can harm your partner.
Also, please note that the most important thing safety-wise is the use of the strap-on dildo. Because the wearer does not feel anything, having constant communication with the receiver is essential. Don’t be stingy with the lube, and always use lube that is compatible with the dildo material. We suggest you use a quality water-based lube and apply it regularly during play.
Strap-On Harness Use Suggestions
People use strap-on harnesses and various strap-on dildos to prolong sexual play. A man can wear a hollow strap-on dildo and continue having intercourse even after he’s ejaculated. In another scenario, the man can put on a hollow dildo strap-on and penetrate their partner, as the decreased sensation allows them to last longer.
Men with ED can find this model extremely useful, as penetration, which is usually impossible for men with ED, is a real possibility by using a strap-on harness with a hollow dildo attached to it.
An exciting sexual activity where strap-on harnesses are essential is pegging – an activity where the male partner is penetrated by a female partner with a dildo or another phallic object. The action stimulates the prostate which can lead to deeper, stronger orgasms in men. Instead of using a handheld dildo, a suitable strap-on harness with a pegging dildo can be the perfect option.
Even oral sex is a thing with a strap-on harness and a suitable dildo, as many couples love the visual turn-on. Using a strap-on harness with a suitable dildo is the perfect option for female-on-female sex, where one partner wears the harness and vaginally or analy penetrates the other partner. We leave further strap-on harness applications to your imagination.
Cleaning & Storage Tips
Cleaning your harness depends on the material it is made from. In most cases, you can throw strap-on harnesses made from woven nylon or microfiber in an underwear bag and wash them in a washing machine on a cold cycle. Please note that these should not be dried in a dryer as the heat can ruin them.
Leather strap-on harnesses are more challenging to clean, as these need a hot water wash and conditioning of the leather to protect it from stiffening up or cracking. Faux leather (leatherette) can be spot-cleaned but not wholly washed with water, as it can deform from the warm water.
After you clean and dry your strap-on harness, we suggest you store them in a protective bag to avoid them getting tangled with other items. Also, please note that you should store them in a dry, cool place, away from heat and direct sunlight. An underwear drawer is a suitable storage place.
The Bottom Line
Overall, using a strap-on harness allows your imagination to run wild so you and your partner can explore new sexual horizons. Nothing stops you from getting several models, trying and comparing them until you find the one that fits you best. Lucky for you, our store is stocked with excellent strap-on harness selection, as well as a variety of other exciting sex toys that fit anyone’s wishes.

FAQs
What happens if I want to use a larger dildo on my harness?
We suggest you always use a dildo that is compatible with your strap-on harness, and this relates to the size of the O-ring diameter and the base of the dildo. Another thing to note is that you should not use dildos that are too long with your strap-on harness, as this can be too heavy for comfortable use.
What is the ideal O-ring size for pegging my husband?
We always suggest you start low and go slow. Since the anus is much tighter and does not self-lubricate, you should use a pegging dildo specifically designed for anal penetration. In terms of O-ring size, these are usually about 1.25-inch diameter and are made from body-safe silicone. However, this is a personal matter, and a matter you should discuss with your husband.
