Setting Up A7 in Design Tools and Print Software
Getting the document size right before you start designing saves a lot of pain later. A7 is 74 x 105 mm, and every tool covered here lets you enter that as a custom size.
One thing most people skip: set up your bleed and safe zone at the start, not at the end. Moving content around after the fact when you realize your artwork does not extend to the edge is genuinely annoying.
Adobe InDesign Setup
File > New > Document. Set Width to 74 mm and Height to 105 mm. Under Bleed and Slug, enter 3 mm on all sides.
Keep your safe zone at least 3 mm inside the trim line. Text and logos that bleed into that margin will likely get cut in production. According to PrintNinja, the commercial printing standard halftone screen is 150 lpi, which is exactly why 300 DPI is the minimum resolution you need in your placed images.
Export as PDF (Print) using the PDF/X-1a preset. That locks down color, fonts, and bleed settings in one go. InDesign is the industry preference for multi-page A7 booklets or sets of cards with consistent grid structures.
Adobe Illustrator and Photoshop
In Illustrator: File > New, set units to millimeters, enter 74 x 105 mm, and add a 3 mm bleed in the Advanced options. Work in CMYK color mode from the start since switching later can shift colors unpredictably.
Photoshop follows the same logic. New document, set dimensions to 74 x 105 mm at 300 DPI, color mode CMYK. Flatten layers before export. Printivity confirms 300 PPI is the optimal resolution for digital presses, and that goes for small-format pieces just as much as larger ones.
Canva and Affinity Publisher
Canva does not have a native A7 preset, but you can set a custom size at 74 x 105 mm under the Custom Size option. The limitation is that Canva designs for screen by default, so exporting for print requires manually selecting the PDF Print option with crop marks enabled.
Affinity Publisher handles A7 cleanly. File > New, enter dimensions, set bleed, and work in CMYK. In 2024, Canva acquired Serif (the company behind Affinity), making the Affinity suite available for free, which removes a previous cost barrier for smaller studios.
| Tool | A7 Setup Method | Best For |
| Adobe InDesign | New Document, 74 x 105 mm + 3mm bleed | Multi-page sets, professional print |
| Adobe Illustrator | New, mm units, 74 x 105 mm + bleed | Single cards, vector-heavy designs |
| Adobe Photoshop | New, 74 x 105 mm, 300 DPI, CMYK | Photo-based A7 cards |
| Affinity Publisher | New, mm, 74 x 105 mm + bleed | Professional desktop publishing |
| Canva | Custom size, PDF Print export | Quick layouts, non-commercial work |
One thing to check before submitting any A7 file to a commercial printer: confirm whether they want CMYK or accept RGB with conversion. Most commercial offset presses print in CMYK, and an unconverted RGB file can produce unexpected color shifts on press. If you need to convert, knowing how to convert RGB to CMYK in Photoshop before sending files will save you a reprint.
For pixel-to-unit conversions during setup, a PX to CM converter or a CM to PX converter can speed up the process when switching between software that uses different default units.
A7 Envelopes and Matching Formats
Here is where things get genuinely confusing: “A7 envelope” means different things depending on where you are buying.
In the ISO system, an A7 envelope would theoretically be sized to carry an A7 sheet. In US stationery retail, “A7 envelope” refers to a 5.25 x 7.25 inch (133 x 184 mm) envelope designed to hold a 5 x 7 inch card. That is a completely different size from ISO A7 paper (74 x 105 mm).
ISO A7 Paper and Its Envelope Match
If you are working with ISO A7 paper (74 x 105 mm) and need an envelope that fits it flat, the correct match is a C7 envelope at 81 x 114 mm.
C7 gives roughly 7 mm of clearance on each side, which is enough for a clean insert without the card sliding around. The C-series is defined in ISO 269 and is specifically designed to hold A-series paper. A C7 envelope holds an A7 flat, or a folded A6.
The US “A7 Envelope” Confusion
The US stationery industry uses “A-size” envelope naming that does not correspond to ISO paper sizes. The US A7 envelope (5.25 x 7.25 in) is designed for 5 x 7 inch cards, which are larger than ISO A7.
Key distinction:
- ISO A7 paper: 74 x 105 mm (2.91 x 4.13 in)
- US “A7” envelope: 133 x 184 mm (5.25 x 7.25 in)
- C7 envelope (ISO match for A7 paper): 81 x 114 mm
This matters most when ordering stationery from mixed-standard suppliers or working on international print projects. According to Searles Graphics, US A7 envelopes are among the most common choices for wedding invitations and greeting cards in North America, which means the term “A7 envelope” is widely understood in that context on that side of the Atlantic.
Practical Buying Guide
Working in Europe or with ISO standards? Ask for C7 envelopes to match your A7 paper sheets.
Working in the US with 5 x 7 inch invitation cards? The “A7 envelope” is the right term for your local supplier. Just verify dimensions before ordering in quantity.
For folded A7 formats, a folded A7 sheet (which produces an A8-sized card at 52 x 74 mm) fits inside a C8 envelope. Worth knowing if you are designing a folded notecard rather than a flat piece.
Understanding paper thickness also matters when choosing envelopes. Heavier card stock (300 GSM and above) can make flaps harder to seal and may require hand-feeding through postage machines rather than bulk processing. And if you are weighing up matte vs glossy paper for the card itself, matte tends to feel more formal and is the more common choice for invitation suites.
What is A7 Paper Size
A7 paper size is 74 x 105 mm (7.4 x 10.5 cm, or 2.91 x 4.13 inches). It sits in the ISO 216 A-series between A6 above it and A8 below.
Each size in the A-series is exactly half the area of the one before it. So A7 is half an A6, and two A7 sheets placed side by side match the dimensions of a single A6 sheet exactly.
The standard is governed by ISO 216, first formalized in 1975 from the German DIN 476 system. Today it is used in almost every country except the United States, Canada, and parts of Latin America.
ISO 216 sets a tolerance of plus or minus 1.5 mm on the shorter side and plus or minus 2 mm on the longer side for A7. These small variances are acceptable in commercial printing without affecting fit or usability.
A7 Aspect Ratio
All A-series sizes share the same 1:root 2 aspect ratio (approximately 1:1.414). This is what makes scaling between sizes work without distortion or cropping.
It also means designs built for A7 can be scaled up to A6 or down to A8 without redrawing layouts. That math is baked into every size in the series.

A7 Dimensions in All Units
Here are the exact A7 paper dimensions across all measurement systems you are likely to need.
| Unit | Width | Height |
| Millimeters | 74 mm | 105 mm |
| Centimeters | 7.4 cm | 10.5 cm |
| Inches | 2.91 in | 4.13 in |
| Pixels at 72 DPI | 210 px | 298 px |
| Pixels at 96 DPI | 280 px | 397 px |
| Pixels at 150 DPI | 437 px | 620 px |
| Pixels at 300 DPI | 874 px | 1240 px |
For print work, 300 DPI is the standard resolution. A7 at 300 DPI gives you a file of 874 x 1240 pixels. Anything lower than 150 DPI will look soft when printed, especially on coated stock.
If you are working in pixels and need to convert, a PX to MM converter or a PX to inches converter will save you the manual calculation. Or if you are going the other way, use a MM to PX converter.
A7 vs Adjacent Sizes
A6: 105 x 148 mm. Exactly double the area of A7. Common for postcards and small notepads.
A7: 74 x 105 mm. The subject here. Used for pocket cards, tags, and compact stationery.
A8: 52 x 74 mm. Half the area of A7. Used for very small tags and mini labels.
The overlap in dimension numbers is not a typo. A7’s height (105 mm) is the same as A6’s width (105 mm). That is how the halving system works.

Where A7 Paper is Used
A7 hits a practical sweet spot. It is small enough to be compact and portable, but large enough to carry real information or a proper design.
Everyday Stationery and Personal Use
Pocket notebooks, folded notecards, and flashcard sets are the most common personal uses. A7 fits comfortably in a jacket pocket or wallet without folding.
Study aids in particular benefit from A7. The format is just large enough for a diagram or a short paragraph, which makes it popular for revision cards and quick reference sheets.
Business and Retail Print
This is where A7 gets used at scale.
- Product hang tags on clothing and retail goods
- Gift tags, available flat or folded with a punched hole for ribbon
- Small promotional flyers and discount vouchers
- Branded thank-you cards included with e-commerce orders
A7 is a standard format at many commercial print houses, which means pre-cut pads and blanks are easy to source and competitively priced. Using it avoids the setup fees that come with custom die-cut sizes.
Events and Invitations
Wedding save-the-dates, event invitations, and place cards often use A7. Printed flat, it holds enough space for all necessary details plus a photo or design element. Folded in half, it produces a compact A8 card.
Many couples pair A7 invitations with print finishes like soft-touch laminate or spot UV to add a tactile quality that digital communication cannot replicate.

A7 in the ISO 216 Paper Size System
ISO 216 organizes paper into three series: A, B, and C. A7 sits in the A-series, which runs from A0 down to A10.
The A-series is built on one mathematical rule. Start with A0 at exactly 1 square meter. Halve it to get A1. Halve that to get A2. Keep going. Every size keeps the same 1:root 2 aspect ratio throughout.
| Size | Dimensions (mm) | Common Use |
| A5 | 148 x 210 mm | Booklets, notepads, and flyers |
| A6 | 105 x 148 mm | Postcards, pocket books, and invitations |
| A7 | 74 x 105 mm | Pocket calendars, small flyers, and notecards |
| A8 | 52 x 74 mm | Mini labels, business cards, and small tags |
| A9 | 37 x 52 mm | Price tags, tiny labels, and coupons |
ISO 216 became the official UN document format in 1975. It is now the standard in almost every country outside North America. The consistent aspect ratio is the reason a design scaled from A7 to A6 needs no adjustment to proportions.
Where A7 Fits Within the Series
A7 is toward the smaller end of practical print formats. Sizes above A5 are mostly used for documents and publications. Below A7, sizes get specialized fast.
A6 is a postcard. A7 is a notecard or tag. A8 and smaller are for labels and micro-stationery. Knowing where A7 lands in that sequence helps when choosing between sizes for a project.

A7 vs US Letter and Other Non-ISO Sizes
There is no direct US equivalent to A7. The closest standard US format is the 3 x 5 inch index card (76.2 x 127 mm), which is slightly wider and taller than A7’s 74 x 105 mm.
A7 Compared to Common Non-ISO Formats
Index card (3 x 5 in): 76 x 127 mm. The most similar US size, but not a match. The index card is taller and the aspect ratio differs.
US Letter: 216 x 279 mm. Roughly 8.5 times the area of A7. Not comparable for small-format use.
B7 (ISO B-series): 88 x 125 mm. Larger than A7. B-series is used far less often in general print work, though it does appear in passport booklets.
Practical Notes for US-Based Buyers
US print buyers ordering A7 from European or international suppliers sometimes run into confusion. The dimensions will be listed in millimeters and the paper weight in GSM rather than pounds.
A 250 GSM A7 card is roughly equivalent to 92 lb cover stock in US terms. Worth knowing before you approve a proof.
Also worth knowing: in American stationery retail, “A7” sometimes refers to a 5 x 7 inch card (127 x 178 mm), which is a completely different size from ISO A7. If you are ordering internationally, confirm which standard your supplier is using.

A7 Paper Weight and Stock Options
The right paper weight for A7 depends entirely on what the piece needs to do. A gift tag needs to hold up to handling. A pocket notepad page just needs to take ink cleanly.
GSM Ranges by Use Case
Church Paper’s cardstock guide (2024) breaks it down clearly by weight category:
- 80-100 GSM: Writing paper, pocket notebook sheets, internal notepads
- 170-229 GSM: Decent for postcards and folded cards where cost matters
- 250-300 GSM: Standard for product tags, notecards, and event invitations
- 300+ GSM: Premium feel for wedding stationery and high-end retail tags
For most A7 card applications, 250-350 GSM is the practical range. It is heavy enough to feel substantial in hand without causing feed issues in digital presses.
Coated vs Uncoated Stock
Coated stock gives sharper color reproduction and is better for photographic or detailed designs. Uncoated is easier to write on and has a warmer feel, which is why most handwritten notecards and tags use it.
According to VistaPrint’s paper weight guide, most home printers struggle with stock over 300 GSM, so anything above that threshold is better ordered through a commercial printer.
Where to Source A7 Stock
Pre-cut A7 sheets and pads are stocked by most paper merchants and office suppliers. For heavier card stock in bulk, specialist print suppliers like Neenah Paper carry A-series dimensions as standard cuts.
One thing worth checking: some suppliers sell A7 paper in packs cut slightly large to allow for bleed trimming. Confirm whether the sheet dimensions listed are the finished trim size or the pre-cut sheet size before ordering.
Understanding paper types in print design more broadly will also help when deciding between silk, uncoated, and textured finishes for A7 projects. And if you are comparing cost versus quality, the difference between uncoated vs coated paper stock is worth reading through before committing to a print run.

FAQ on A7 Paper Size
What are the dimensions of A7 paper?
A7 measures 74 x 105 mm, or 7.4 x 10.5 cm.
In inches, that is 2.91 x 4.13 in. It follows the ISO 216 standard, sharing the same 1:root 2 aspect ratio as every other size in the A-series.
What is A7 paper used for?
Common uses include gift tags, product hang tags, pocket notecards, and small invitations.
It also works well for flashcards, folded thank-you cards, and compact promotional print pieces. The sheet size is practical enough to carry real information without feeling oversized.
How does A7 compare to A6 and A8?
A6 is exactly double the area of A7, at 105 x 148 mm. A8 is half, at 52 x 74 mm.
Two A7 sheets placed side by side match one A6 sheet exactly. That is the halving principle built into every ISO 216 paper size.
What is A7 paper size in pixels?
At 300 DPI, A7 is 874 x 1240 pixels. That is the resolution you need for sharp commercial print output.
At 72 DPI it is 210 x 298 pixels, and at 96 DPI it is 280 x 397 pixels. Use a PX to MM converter if you need to switch between units quickly.
Is A7 the same as a 3×5 index card?
Not quite. A US index card is 76.2 x 127 mm, slightly wider and taller than A7’s 74 x 105 mm.
The aspect ratios also differ. There is no exact US equivalent to ISO A7, though the index card is the closest standard format available in North America.
What paper weight should I use for A7 cards?
For product tags and notecards, 250-350 GSM is the practical range. It feels substantial without causing feed issues in most digital presses.
Lighter stock around 80-100 GSM works for pocket notebook sheets. Wedding or premium stationery typically goes to 300 GSM and above. See paper weight vs thickness for a full breakdown.
What envelope fits A7 paper?
A C7 envelope (81 x 114 mm) is the correct ISO match for a flat A7 sheet. It gives around 7 mm of clearance on each side.
Note that US stationery suppliers use “A7 envelope” to mean a 5.25 x 7.25 inch envelope, which is a completely different size. Always confirm dimensions when ordering internationally.
How do I set up A7 in Adobe InDesign?
Go to File > New > Document. Set Width to 74 mm and Height to 105 mm. Add a 3 mm bleed on all sides under Bleed and Slug.
Export as PDF/X-1a for print. Keep text and logos at least 3 mm inside the trim line. Check out the full guide on how to set up a print-ready file if you want to cover all bases.
What is the difference between A7 paper and an A7 envelope?
ISO A7 paper is 74 x 105 mm. A US “A7 envelope” is 133 x 184 mm. They are not related.
The US naming uses a separate stationery convention that does not follow ISO 216. If you are outside North America and need an envelope for A7 paper, ask for a C7 envelope instead.
Is A7 a standard paper size worldwide?
Yes, in most of the world. ISO 216 is used in almost every country except the United States, Canada, and parts of Latin America.
Within the A-series, A7 is a recognized standard sheet size. Pre-cut A7 paper pads and blank cards are stocked by most commercial paper suppliers and print houses globally.
Conclusion
This conclusion is for an article presenting everything you need to know about A7 paper size, from exact sheet dimensions and pixel counts to stock weights, software setup, and envelope matching.
At 74 x 105 mm, A7 fills a specific gap in the ISO 216 A-series. Small enough for a gift tag or pocket notecard, large enough to carry a real design.
Knowing the difference between a C7 envelope and a US “A7 envelope” alone can save a misprinted run. Getting your 300 DPI file set up correctly before sending to a commercial printer matters just as much.
Whether you are working in InDesign, Affinity Publisher, or Canva, the setup process is straightforward once you know the trim size, bleed, and safe zone requirements for this print format.
A7 is a practical, well-supported paper specification. Use it right and the results speak for themselves.
