I think this warrants a special focus upon. The post will be edited and updated as we go to reflect the inquiries.
When selecting a cylinder size, make sure to understand the needs for the setup. At the same time, YOU MUST precondition your penis before going into higher pressure. Do not go crazy from 0inHg to 10inHg because you think you can. You must condition your penis slowly and safely unless you want a broken penis, or at minimal, edemas and injuries.
This is not an exhaustive table. It's just a starting point. Do provide more questions and the table will be updated as we go.

- Water and air, or simply air only usage.
- What you're trying to achieve.
- What your main focus in the long run, such as girth, ED, or correction of anomolies.
| Focus of pumping | Current size | Objective size (height and in circumference) | Cylinder size (height and in circumference) | Notes |
|---|---|---|---|---|
| Erectile Dysfunction (ED) | Your current girth and length | 1in (2.5cm) or less | 2in taller than your current size and 0.5in (1.27cm) larger than your current circumference | When using water, you need head space for proper pressure buildup. A small amount of buffer space is needed around the penile shaft to provide proper blood flow and expansion. You are trying to promote blood flow through force expansion. You can upgrade your cylinder later on if needed. |
| Girth gain, but have no issue with achieving normal erection | Your current girth and length | Gaining as much girth as fast as you can. | ALWAYS have 2in taller than your ending objective girth and length objective size and at least 1.5in larger than your current size. | When pumping, your penis should be force to expand at least 30% your current girth size. The optimal is 50% bigger than the current girth size. Best is close to twice as large without edemas and fluid retention. Always have max erection inside the cylinder during pumping. |
| Girth gain, but have issue with achieving normal erection due to ED. | Your current girth and length | Gaining as much girth as fast as you can, but maintain erectile rigidity | ALWAYS have 2in taller than your ending objective girth and length goal size, where the first cylinder is 0.5in larger than your current size. The second cylinder should be 1in larger than your current size. Some just skip 1in larger and go straight to 1.25in instead. Optional third cylinder should be 1.5in larger than your current size. | This is call "Step Up". To prevent sudden drop on penile rigidity or erection quality due to extreme fatigue because you over work your penis from pumping, you may want to step up the pumping one size at a time. Why? You're using the cylinder wall to maintain the expansion from going out of control, causing your corpa cavernosa and spongiosum (your blood chambers) from weakening too fast. This is perfect for sexual plays after pumping. |
| Length gain through pumping, but also focus a bit on girth | Your current girth and length | Gaining as much length as fast as you can. | ALWAYS have 2in taller than your ending objective length and objective gain, where the first cylinder is 0.25in larger than your current size. The second cylinder should be 0.75in to 1in larger than your current size. | You try to restrain expansion and force elongation instead. All blood pressure will force upwards toward your glans. Tissues will break down faster on the latter second half of your penis and force upward growth instead. Lubrication will be needed as the penis will moves up and down quite dramatically under vacuum pressures. |
