Custom C4 Envelopes
Price Calculator
A C4 envelope measures 229 × 324 mm — that is 22.9 × 32.4 cm or 9 × 12.8 inches (9.02 × 12.76 in exact). It holds an A4 document flat, without folding. Tagsen prints custom C4 envelopes on 100 GSM paper from ₹19 per piece, minimum 100 pieces.
What Is a C4 Envelope?
C4 is part of the ISO 216 C-series, the international standard for envelope sizes. Each C-size is built to hold the matching A-size sheet, which is why C4 pairs with A4. An A4 page is 210 × 297 mm, so the envelope is about 19 mm wider and 27 mm taller — enough room to slide documents in without bending the corners.
Is a C4 Envelope the Same as an A4 Envelope?
Yes. There is no official ISO size called an A4 envelope, but because a C4 holds an A4 sheet unfolded, buyers across India call it an A4 envelope. If you searched for A4 envelope size, 229 × 324 mm is the size you need. If your document can be folded, a smaller A5 envelope or Long Envelope #10 costs less to print and post — see our full envelope printing range.
Custom C4 Envelope Printing
We print on 100 GSM Alabaster paper — a smooth, opaque stock that takes ink cleanly and hides the document inside. Every envelope has a strong gum seal and square-cut edges built for courier handling. Add your logo, business name, address, GST details or full custom artwork. You can browse our templates, design online, upload print-ready files, or hire our design team. Many customers print matching custom letterheads at the same time.
Price and Who Uses C4 Envelopes
Custom-printed C4 envelopes start at ₹1,900 for 100 pieces — ₹19 per envelope, with per-unit pricing falling at higher quantities. For 500 pieces or more, request a bulk quote.
Businesses use C4 envelopes for proposals, contracts and invoices. Schools send certificates and mark sheets, while banks and CA offices use them for confidential documents that must not be folded. Government tenders almost always specify C4, because official papers are filed flat. Browse our full office stationery range to print a matching set.
