Use this quick reference to match reload color with closed staple height and a typical tissue thickness range.
It’s designed as a practical starting point for selection and training.
Important: Color codes and staple heights can vary by manufacturer/model and by region.
Always verify the exact reload specification in the IFU (Instructions for Use) of your device and follow your institution’s clinical protocols.
The table below includes example placeholders you can adjust to match your product line.

How to use this chart
Identify the reload color code used by your stapler system.
Check the closed staple height (mm) for that reload.
Match to a typical tissue thickness range and scenario.
If uncertain, refer to IFU or your clinical team’s standard.
Tip: Many teams keep a printed copy of this chart in the OR for quick reference and onboarding.
Reload color chart
Replace the “Example” values below with the exact specs of your reloads (from IFU).
| Color code | Reload / cartridge type | Closed staple height (mm) | Typical tissue thickness (mm) | Typical scenarios (examples) |
|---|---|---|---|---|
| White / Gray Thin | Vascular / thin tissue reload | Example: 1.0 – 1.5 | Example: 0.8 – 1.5 | Delicate / thin tissue applications (verify per IFU) |
| Blue Medium | Standard tissue reload | Example: 1.5 – 2.0 | Example: 1.5 – 2.0 | General soft tissue ranges (verify per IFU) |
| Gold Thick | Thicker tissue reload | Example: 2.0 – 2.5 | Example: 2.0 – 2.5 | Moderately thick tissue; consider compression time (verify per IFU) |
| Green Extra thick | Extra-thick tissue reload | Example: 2.5 – 3.0 | Example: 2.5 – 3.0 | Thicker tissue ranges (verify per IFU) |
| Black Very thick | Very thick tissue reload | Example: 3.0 – 4.0 | Example: 3.0 – 4.0 | Very thick tissue; strict IFU compliance recommended |
FAQ
Do all stapler systems use the same color codes?
No. Many systems use similar color conventions, but exact meanings and staple heights can differ by manufacturer and model. Always confirm with the device IFU and approved reload compatibility.
What is “closed staple height” and why does it matter?
Closed staple height is the final formed height of the staple after firing. It should match the tissue thickness range to help achieve reliable formation and apposition. Selecting the wrong height can increase the risk of poor formation.
How do I estimate tissue thickness?
Estimation methods vary by institution and procedure. Many teams rely on experience, visual cues, device feedback, and IFU guidance. This page is a reference chart only — not a clinical instruction.
Can I use a thicker reload “just to be safe”?
Not always. A reload that is too tall for thin tissue may reduce compression and affect staple formation. The safest approach is to follow IFU-recommended ranges and your clinical protocol.
