9x12 postcard template and specs

A 9x12 community card is a print job with unforgiving constraints: it has to trim cleanly, it has to satisfy USPS EDDM requirements, and it has to carry ten to sixteen advertisements that are all still legible after printing.

Here are the specifications, then the layout decisions that matter.

Exact dimensions

Measurement	Value
Trim size	9″ × 12″
Orientation (community cards)	Landscape — 12″ wide × 9″ tall
Canva document size	12″ × 9″ — the trim size
Bleed	0.125″ on all four edges, added by Canva on export
Print file size with bleed	12.25″ × 9.25″
Safe zone inset from trim	0.25″
Live area	11.5″ × 8.5″
Resolution	300 DPI at final size
Color mode	CMYK

Build at 12 × 9 and keep everything that must not be cut inside 11.5 × 8.5. Every reprint anyone has ever paid for in this business is because a phone number sat outside the safe zone and the trim took the last two digits.

The 12.25 × 9.25 figure is what the finished print file measures once bleed is included. It is not what you type into Canva — Canva adds that margin itself at export, so building at 12.25 × 9.25 gets you a card a quarter-inch too big.

Cardstock and finish

14pt coated cover is the standard. It survives the mail stream, it is what most EDDM printers quote by default, and it is the cheapest option that does not feel cheap.

16pt costs modestly more per piece and is noticeably more substantial in the hand. If you are selling anchor spots at $900+, the upgrade pays for itself in how the card presents when you are holding it in a sales conversation.

Gloss vs matte: gloss makes photography pop and is the default. Matte or soft-touch reads as more premium but suppresses color saturation, which advertisers with bright logos will notice. UV coating on one side only is a common compromise.

The EDDM requirements

The address side must carry:

• The EDDM indicia in the upper right
• The ECRWSS endorsement
• A clear address block area — for EDDM this is where the “Local Postal Customer” line goes
• Your permit information, or your printer’s if they are mailing for you

Use your printer’s indicia artwork. If they are mailing under their permit, building your own is the fastest route to a rejected drop at the counter.

For the size rules themselves, verify against current USPS specifications before you commit a run. EDDM’s flat-size limits are the entire reason this format is economical, and they are the one thing you cannot design around.

Laying out the ad spots

This is where most templates fall down, because a template gives you a grid and the grid is not the hard part — legibility at print size is.

How many spots

Ten to sixteen. Below ten and each spot has to be priced past what a small local business will pay without a long conversation. Above sixteen and the small spots stop being readable, which is how you lose renewals — an advertiser whose ad nobody could read does not buy again.

A grid that works

A 12″ × 9″ face divides comfortably into a 4 × 3 arrangement of roughly 2.75″ × 2.75″ cells, with the live area giving you a bit under that. From those twelve cells you build mixed sizes:

Spot	Cells	Approx printed size	Typical price
Anchor / mega	2 × 2	5.5″ × 5.5″	$900 – $1,500
Large	2 × 1	5.5″ × 2.75″	$700 – $900
Medium	1 × 1	2.75″ × 2.75″	$400 – $600
Small	half cell	2.75″ × 1.35″	$200 – $350

Minimum type sizes

Non-negotiable, because these are the sizes at which a reader in their fifties standing at a mailbox can actually read an ad:

• Business name: 18pt minimum
• Offer / headline: 14pt minimum
• Phone number: 14pt minimum, and never reversed out of a photo
• Body and disclaimers: 8pt absolute floor

If an advertiser’s artwork does not clear these, fix it before it prints. It is your card that looks bad, not theirs.

Leave room for tracking

Every spot should have space for a distinct phone number, a QR code, or a coupon code. This is the single highest-value square inch on the card, because it is what tells the advertiser the card worked, and that is what makes them renew. Design it in from the start rather than squeezing it in later.

Building the card in Canva

The templates at the top of this page already have the document size, the guides and the spot grid in place. If you are building from a blank document instead, the sizes and the four setup steps are in that same block.

Either way, two decisions are yours:

1. Build the spot grid as locked rectangles so an advertiser’s artwork drops into a fixed box rather than resizing the layout.
2. Design the address side second, with the indicia and address block clear.

Canva will produce a perfectly good print file. What it cannot do is know that square 4 costs $500, that it sold on Tuesday, and that the price on the card and the price the advertiser paid have to be the same number — which is the actual operational problem in this business.

The five mistakes that cost a reprint

1. Content outside the safe zone. Phone numbers and logos clipped at trim.
2. RGB artwork from an advertiser. Bright RGB blues and greens shift dramatically in CMYK. Convert and check before you send the file.
3. Low-resolution logos. A 72 DPI logo pulled off a website looks fine on screen and pixelated at 9x12. Ask for vector or 300 DPI.
4. Wrong quantity. EDDM means every address on the route. Your print count is the sum of the household counts, not a round number.
5. A price on the card that does not match what was charged. Not a print error, but it is the one that costs you the advertiser.

Print-ready guide files

Only if you are handing this to a designer or a print shop. If you are building it yourself in Canva, the sizes above are all you need — skip this.

Each file is the print size with the trim line, the safe area, and crop marks already in place — bleed included in the file rather than added at export.

After the template

The file above solves the print geometry. It does not solve the part that comes after: one file for the layout, another place for prices, a third for who has paid.

The card builder here handles all five formats — 6×11, 6.5×12, 9×12 landscape and vertical, 8.5×11 — with bleed and safe zones locked, drops each advertiser’s finished artwork into their square, and keeps the price on the card and the price in the checkout as the same number, because they are the same number.
