Plywood availability — what is the typical lower-end thickness range in which commercial plywood sheets are normally supplied? Pick the most appropriate range.

Introduction / Context:
Plywood is manufactured by cross-laminating veneers to produce sheets with improved dimensional stability and strength. Commercial availability spans a range of standardized thicknesses depending on grade and application (furniture, paneling, shuttering, etc.).

Given Data / Assumptions:

• Considering common commercial plywood (not specialty veneer or aircraft-grade exceptions).
• Focus is on the typical lower-end sheet thickness readily available.
• Regional standards may vary slightly, but common practice applies.

Concept / Approach:
In many markets, the thinnest widely available plywood sheets start around 3 mm to 4 mm for general use. Ultra-thin 1–2 mm sheets are usually veneers or specialty products, not standard plywood stock for typical building/furniture work.

Step-by-Step Solution:

Verification / Alternative check:
Supplier catalogues and building material standards commonly list 3–4 mm as the thinnest routine plywood options.

Why Other Options Are Wrong:

• 1 mm, 2 mm, 2–3 mm: These are veneer/specialty ranges, not standard plywood sheets for general distribution.

Common Pitfalls:
Confusing veneer thickness with plywood sheet thickness; plywood is multiple veneers cross-laminated.

Final Answer:
3 mm to 4 mm thick
