Envelope A4

Description

📄 What “Envelope A4” Means

• A sheet of A4 paper has dimensions 210 × 297 mm (approximately 8.3″ × 11.7″) by international standard.

• To hold an A4 sheet flat (i.e. without folding), you don’t actually use an envelope labeled “A4” — you use a C4 envelope (or similar). C4 size is 229 × 324 mm (≈ 9.0″ × 12.8″), giving a little extra room to fit the A4 sheet comfortably.

• If you fold the A4 sheet in half, it fits into a C5 envelope (162 × 229 mm).

👉 Many suppliers or users may loosely say “A4 envelope” to mean “an envelope for A4 paper,” but technically the correct envelope size for flat A4 is C4.

✉️ What to Look for in a Good Envelope for A4 Documents

• Material and weight: Paper or manila envelopes — heavier paper (e.g. ~90 gsm) helps keep documents safe and durable.

• Size / fit: For sending A4 documents or certificates without folding, get C4 (229×324 mm). If you will fold documents, C5 is okay.

• Closure type: Sealable flaps (self‑seal, peel‑and‑seal, gummed) help secure contents inside, useful for mailing or safe transport.

• Color / style: White/pale envelopes for official documents, or manila/brown for regular files — depending on use.
