Measurement Tips: Are You Measuring Correctly?

Insertable Length

Measure from: Base (the widest part where insertion begins)

Measure to: Insertion terminus (where the toy would no longer advance inside the body)

Exclude:

• Handle or retrieval feature
• Suction cup (if present)
• Decorative flanges or balls

Example: A dildo with a 6" shaft and a 1" suction cup base = 6" insertable length, not 7"

Diameter

Measure at: The widest point of the bulb (usually mid-shaft)

Exclude:

• Narrow neck
• Base flange
• Textured ridges (measure core width)

How to measure without callipers:

1. Wrap string around widest point
2. Measure string length with ruler
3. Divide by 3.14 (π) to get diameter

Example: A toy with 4cm circumference at widest point = 4 ÷ 3.14 = 1.27" diameter

Size Progression Roadmap

If exploring size over time:

Month 1–2: Petite (3–4", 1–1.2") — comfort and learning

Month 3–4: Standard (4–5", 1.2–1.4") — sensation discovery

Month 6+: Average+ (5–6", 1.2–1.4") — satisfaction plateau

Month 9+: Extended (6–7", 1.4–1.6") if interested — depth exploration

Month 12+: Girthy (1.6–1.8") or Deep (7–8") if desired — niche exploration

This progression is common among satisfied users. Not all reach the endpoint; most stop at Average+ (5–6", 1.2–1.4").

Common Sizing Mistakes to Avoid

Mistake 1: Starting large

Buying 7+ inches before establishing comfort at average sizes. Results in discomfort and abandonment.

Avoid by: Starting at 5–6 inches; upgrading if desired after 3+ months.

---

Mistake 2: Confusing total length with insertable length

Buying a toy with 7" total length, 5" insertable, expecting 7" sensation.

Avoid by: Always measuring only the insertable portion.

---

Mistake 3: Ignoring material's effect on size

A soft 1.3" toy feels different than a firm 1.3" toy.

Avoid by: Factoring material (Shore A hardness) into size decisions.

---

Mistake 4: Assuming diameter matches girth sensation

Circumference (what you feel) differs from diameter (what you measure).

Remember: 1.3" diameter = ~4.1" circumference. A "1.3-inch" toy has 4.1" of girth.

Final Size Selection Logic

1. Identify your experience level. Beginner? Start Standard (4–5", 1.2–1.4").

2. Consider your focus: Length-sensation (depth) or diameter-sensation (stretch)?

3. Check vaginal depth: ~10 inches relaxed, ~12 inches aroused. This caps practical insertable length.

4. Account for material: Soft silicone feels smaller; firm silicone feels larger.

5. Plan progression: If exploring size, choose an entry point and progression path.

6. Use filters: Set length and diameter on Measured Pleasure; browse results.

7. Read reviews: Real users report comfort/discomfort. Trust pattern consensus.

Most users find satisfaction in the Average+ tier (5–6", 1.2–1.4") and remain there indefinitely. This is not limitation; it's optimal fit.
