Gratuity envelopes should fit the cash you intend to give, close properly and make the recipient easy to identify. For unfolded U.S. bills, start with an envelope around 3.5 by 6.5 inches. For a small, discreet handoff, a compact envelope works if you are comfortable folding the money. The important distinction is usable space, not whether a listing calls the product a tip, coin, seed or gift envelope.
A plain envelope with a handwritten name can work for a hotel stay, salon appointment or event. A business distributing tips may prefer printed identification fields. Choose the format around the handoff, then check the exact size, closure and quantity before comparing the total cost.
Choose the size around the bills
The U.S. Currency Education Program gives the familiar small-size banknote dimensions as 6.14 by 2.61 inches. That makes the difference between the following envelope formats substantial. The fit notes below are dimensional comparisons, not hands-on capacity tests; seams, paper thickness and a stack of notes reduce usable room.
| Envelope format | How U.S. bills compare | Useful starting point |
|---|---|---|
| 3.5 × 6.5 inches | Larger than an unfolded 2.61 × 6.14-inch note | Keeping bills flat and adding a short note |
| 3 × 3.5 inches | A bill folded across its length becomes about 3.07 × 2.61 inches | A compact handoff with one fold |
| 2.25 × 3.5 inches | A once-folded 3.07 × 2.61-inch bill remains too wide | Coins or bills folded smaller in both dimensions |
For that smallest format, folding in both directions produces a rectangle about 3.07 by 1.31 inches before allowing for thickness. Do not assume that folding a bill in half once will fit every coin envelope. If you are using another currency, measure its largest note rather than applying U.S. dimensions. A rigid gift card and its cardboard holder also need their own fit check.
Three clearly different options
Blue Summit Supplies #7: a larger plain cash envelope
The maker’s #7 Coin Envelopes, model BSS-92588-039, measure 3.5 by 6.5 inches and come in a pack of 500. They use 28 lb brown kraft paper, have no window and are specified by the maker with an extra-wide gummed seal. This is the most relevant starting point here if you want to keep ordinary U.S. bills unfolded.
The tradeoff is quantity: 500 envelopes makes more sense for repeated use than for a single weekend away. There is no printed thank-you message, so leave time to label each one. The Amazon page’s title and detailed bullets describe a gummed closure, but its summary field says “PEEL & SEAL.” Confirm the package closure if avoiding moisture is important; those descriptions are not interchangeable.

Uline S-23028BL: small black envelopes for compact presentation
Uline’s black coin envelope S-23028BL is listed at 2.25 by 3.5 inches, with 500 envelopes per case. Uline specifies 60 lb Astrobright Eclipse Black paper, a center seam and an extra-deep gummed flap. The published outside dimensions exclude the flap; its flap length is one inch.
This is a compact option when presentation matters and folded cash is acceptable. The small dimensions are the compromise, and black paper needs a label or a pen whose ink remains readable. Try your chosen pen on a spare envelope and let it dry before stacking. The paper-weight number alone does not establish how its stiffness compares with the kraft option.
E. Greene tip envelopes: identification fields and a permanent closure
E. Greene’s Tamper Evident Tip Envelopes measure 3 by 3.5 inches and have a one-inch permanent peel-and-seal closure. The maker specifies 140# Manila Index stock and fields for employee name, date, shift and amount. It also describes the closure as showing evidence of opening. That is a manufacturer description, not a guarantee against theft.
This format is relevant to an organized staff handoff rather than a decorative thank-you note. The public product page does not state a package quantity, so request the exact envelope count and printing details before comparing a quote with a 500-pack. Because the seal is permanent, complete and check the contents before closing it. Do not buy it expecting a reusable flap.
Gummed, peel-and-seal or an open flap?
A gummed flap needs moisture to activate its adhesive. Follow the package directions, press the flap evenly and allow the seal to set before handling the envelope. A peel-and-seal design has a removable strip over the adhesive. It avoids the moistening step, which can be convenient when preparing several envelopes together.
An unsealed flap is easy to reopen but can release its contents in a bag or pocket. For cash you will carry before handing over, choose a closure you can check. Avoid overfilling: a flap that strains to reach the adhesive area is a reason to use a larger envelope. Do not treat an ordinary paper envelope as secure cash storage.
Keep the handoff discreet and easy to understand
Write the recipient’s name or the service role clearly. Add a brief thank-you if appropriate. When leaving an envelope in a room, make its purpose clear enough that it is not mistaken for paperwork or rubbish. If several people are receiving envelopes, label them before inserting the cash and double-check the recipient at the handoff.
For personal gifts, there is usually no practical need to display the amount on the outside. For an internal workplace process, use the fields and handling procedure your organization actually requires. An envelope does not determine a tipping amount, tax treatment or entitlement, and printed fields should not be mistaken for a complete business record.
Check paper, quantity and presentation before ordering
A windowless envelope avoids an obvious view of its contents, but paper color and weight are not an opacity test. Check a sample under normal lighting if privacy matters. Likewise, a decorative liner or extra card takes up room. Test the complete combination rather than an empty envelope alone.
Count how many handoffs you expect, add a few spares for labeling mistakes and compare like-for-like pack quantities. A large case can leave years of unused stock after a small event. For custom printing, confirm the wording, orientation, envelope size and count in the proof before accepting the design.
If you plan to print at home, check your printer’s supported envelope sizes and feeding instructions first. Small coin envelopes and stiff index stock may need a different approach from ordinary stationery. Handwritten labels are a practical alternative. The right purchase is the smallest quantity of a correctly sized, clearly labeled envelope that closes comfortably around the actual contents.
