How Many Sizes to Include in a Printable Listing

There are two numbers here, and confusing them is the classic printable-seller mistake: how many sizes you advertise, and how many files you deliver. The winning answer is "many" and "five."

Advertise many, deliver five

Etsy hard-caps digital listings at 5 files (20MB each). Meanwhile, buyers search things like "16x20 printable" and "A3 wall art" — and listings that name more sizes match more searches. The resolution:

• Deliver: five ratio masters — 2:3, 3:4, 4:5, 11x14, ISO A.
• Advertise: every size those ratios print: 4x6, 5x7, 6x8, 8x10, 8x12, 9x12, 11x14, 12x16, 12x18, 16x20, 16x24, 18x24, 20x30, 24x36, A5, A4, A3, A2, A1 — 19+ named sizes from five uploads. (Add 5x7 as its own ratio if your composition tolerates a sixth crop; otherwise fold it into the chart with a note.)

Each ratio file prints every size in its family with zero quality tricks — the mechanics are in the printable size guide.

The size chart is the conversion asset

Bundle a one-page chart PDF in the download: three columns — your frame size → open this file → print at this setting. Shops that include one report noticeably fewer "which file do I use?" messages, and the chart doubles as listing image #2, which quietly answers the buyer's fear ("will it fit MY frame?") before they ask.

Worked example: rewriting a 3-size listing

A seller lists a line-art print with three files: 8x10, 16x20, 24x36 JPEGs.

1. Regenerate as five ratio masters from the original art (the Ratio-Pack Generator exports all five in one pass, with per-crop focal adjustment and 300 DPI embedded).
2. Title gains: "…Wall Art, 20+ Sizes Included, A4 A3 A2" — new keyword surface.
3. Description gains a size table naming all 19 sizes.
4. Download gains the size-chart page.

Same art, same $6.50 price, but the listing now matches searches for every frame size and never gets the "do you have 12x18?" message that previously ended in a lost sale. At Etsy's fee structure a $6.50 digital sale nets about $5.42 — see what Etsy takes — so the win has to come from volume, and size coverage is free volume.

When five files aren't enough

Selling exact-pixel files per size (some sellers prefer this for premium packs — buyers just hit print) blows past the 5-file cap fast: 19 sizes × JPEGs won't fit. The standard workaround is grouping sizes into ZIPs by ratio — one ZIP per ratio family, still 5 files. Size math and the splitting technique are in the 20MB limit guide; the international angle (why the ISO file earns its slot) is in A4 vs US Letter.
