How to measure the perfect size for perfect happiness and safety

Introduction: Why is getting "size" right more important than just length?

Sleeves/Extenders are devices that add a new dimension to relationships and self-exploration, but choosing the wrong size can lead to discomfort, circulation problems, or even breakage during use.

This comprehensive guide will help you correctly measure and understand the specifications of your penis enlargement sleeve , so you can get the most enjoyment and safety out of your device.

1. Know the types of sleeves (Sleeve Types)

Before measuring, it's important to understand the purpose of each type of sleeve so you can get the right size for your intended application:

Sheath type	Main usage characteristics	Special considerations
Open-Ended Sleeve	Focuses on increasing girth while maintaining direct contact with the glans.	The circumference of the head must be measured to ensure a snug fit around the sheath edge.
Closed-End Sleeve (Closed End/Solid Head)	Focus on increasing both length and thickness, simulating different sizes.	All lengths and circumferences must be measured as accurately as possible.
Harness/Cock Ring Sleeve	It has a compression strap at the base to emphasize stiffness and durability.	You must measure around the base for a snug fit (important for circulation).

2. The Sizing Protocol

Measurements should be taken when the penis is **fully erect** using a soft measuring tape (Tailor's Tape). For accuracy:

A. Length measurement

Place a ruler or tape measure at the base (the base of the penis where it meets the pubic bone) and measure all the way to the tip of the head.

B. Girth or thickness measurement

Wrap a tape measure around the **thickest** part of your erect penis (usually around the midsection). This measurement is the most important factor in choosing a snug-fitting sleeve.

💡 **Tip:** If you don't have a flexible tape measure, wrap a piece of paper around it, make a mark, and then measure the length with a ruler to convert it to the circumference value.

C. Base Girth measurement for models with a clamp.

Measure around the base and scrotum to ensure the ring is not too tight, which could affect blood flow.

3. Reading and comparing product specifications (Matching Specs)

Compare your measurements to the sleeve's specifications, paying attention to the **Internal Girth** value first:

Specs you can measure	Product specifications you must see	Importance
Your circumference	Internal Diameter/Girth	Most importantly: To make the sheath fit snugly, not too loose or too tight.
Your length	Total internal length (Internal Length)	Determine how tightly the sheath can be covered or how much length can be extended.

**⚠️ Expert Tip:** The penis enlargement sleeve is made of highly stretchable silicone. You can choose a sleeve with an inner circumference that is **slightly smaller** than your own circumference (about 5-10mm) for maximum fit and a less slip-resistant fit.

4. Safety and usage precautions

**Do not tighten too tightly:** If you experience numbness, pain, or feel that blood circulation is blocked, remove the sheath immediately.
**Always use a water-based lubricant:** Using water-based lube both on the outside and inside of the sleeve is essential to prevent friction and injury.
**Hygiene:** Clean the cover after each use to prevent bacteria buildup and maintain the durability of the material.
