All 5 envelope formats are 4.125″ × 9.5″ No. 10 size — the North American standard that fits a tri-folded letter-size sheet and meets every postal automation requirement. The decision matrix: paper weight (60lb standard vs 70lb premium), window option (none, single, or double), and whether the envelope itself is printed with your brand or shipped blank.
Which Envelope Should You Buy?
- Sending cheques or two-window statements? Double Window Blank at $89. Pairs with our Manual Cheques and Premium Laser Cheques — the recipient address and your return address show through the windows, eliminating addressing errors entirely.
- Need cheap envelopes for bulk marketing or routine mail? Standard Office at $159. 60lb stock with your branding. The default for high-volume AR teams.
- Mailing invoices that need the recipient address visible through a window? Standard Office Window at $199. Print your invoices so the address appears in the window position — eliminates separate envelope-addressing.
- Professional services where the envelope itself is a brand impression? Premium Office at $219. 70lb premium paper is noticeably thicker and feels substantial in hand. Standard for law firms, accounting practices and high-end consulting.
- High-volume AR or AP where presentation matters? Premium Office Window at $269. The combination of 70lb premium paper plus single window is the gold standard for invoice mailing at scale.
Window vs No-Window: A Practical Guide
The decision between window and no-window envelopes comes down to workflow:
- No-window envelopes require you to print the recipient address directly on the envelope (via envelope printer feed or a mailing service). More flexible for letters where the inside content varies, but adds a labeling step.
- Single window envelopes let the recipient address printed on your invoice or statement show through. Eliminates the labeling step entirely for AR mailing. Standard for invoice cycles.
- Double window envelopes show both the recipient address AND your return address (printed on the cheque or document inside). Required for cheque mailing where the cheque itself contains the return address. Saves time on every cheque mailed.

Envelope Design Best Practices
- Logo and business name in the top-left corner. Standard return-address position; the recipient sees it before opening.
- Full return address. Required by Canada Post for proper return-to-sender handling on undeliverable mail.
- Keep the right two-thirds clean. The Canada Post automation reads the recipient address by camera. Backgrounds, watermarks or decorative artwork in the address zone cause sorting errors.
- Match your business cards and letterhead. Envelopes + letterheads + business cards as a coordinated stationery kit ships in one shipment.
- For windowed envelopes, position the recipient address in the window zone on your letter, invoice or statement — typically 1″ from left, 2.25″ from top on a standard letter fold.

Frequently Asked Questions
What is the difference between Standard and Premium envelopes?
Paper weight. Standard uses 60lb uncoated; Premium uses 70lb. The 70lb feels noticeably more substantial in hand — the difference is obvious when comparing the two side by side. For high-volume marketing mail, 60lb is plenty. For client correspondence, professional services and legal communications, 70lb is worth the upgrade.
Will window envelopes work with my QuickBooks invoices?
Yes — our single-window envelopes use the standard window position that QuickBooks Online, QuickBooks Desktop, Sage 50, Sage 300, Xero and most accounting software align to by default. Print a test invoice on plain paper, fold it on the standard fold lines, and check that the recipient address appears in the window before committing to a large run.
Do double-window envelopes work with your cheques?
Yes — our double-window blank envelopes are specifically sized so the windows align with the payee and return-address positions on our Premium Laser, Extreme Security, and Manual cheque formats. The standard pairing for any business mailing cheques.
How many envelopes should I order?
500 is the standard quantity — enough for most small businesses for 3 to 6 months. High-volume AR teams (subscription businesses, property managers, accounting practices) often order 2,500 or 5,000 at a time for better per-piece pricing.
Can I get the envelopes shipped blank for me to print later?
Yes — our Double Window Blank format at $89 ships unprinted, which is the working norm for businesses sending cheques. If you want blank versions of any other format, call us and we can quote.
Are these envelopes compatible with my office printer for over-printing?
Yes — our envelopes work in most standard laser and inkjet office printers if you want to over-print recipient addresses on no-window envelopes. Test a few in your printer first; envelope feed is one of the touchier parts of office printing.
Can I get matching letterhead and business cards?
Yes — envelopes + Premium Letterheads + business cards ship together as a coordinated stationery kit.
