How Big Is 11×17 Paper? | Quick Size Guide

What 11×17 Actually Measures

In plain numbers, 11×17 is exactly 11 inches wide and 17 inches tall when used in portrait orientation. In metric terms that’s 279.4 by 431.8 millimetres, or 27.94 by 43.18 centimetres. Across North America, the same sheet appears under different names: “Tabloid” when you hold it tall, and “Ledger” when you rotate it wide. The engineering series calls it “ANSI B.”

If you landed here wondering how big is 11×17 paper for day-to-day work, the takeaway is simple: it’s a mid-size sheet that gives more room than Letter without jumping into plotter territory. When a team asks how big is 11×17 paper during planning, think posters, charts, or folded handouts that still run on many office copiers.

One more sizing detail helps with layout math: the 11×17 aspect ratio is 17 ÷ 11, which is about 1.5455. That number explains why a layout that fits Letter sometimes still feels tight when scaled up; the shape is wider relative to height. If your design depends on strict proportions, lock a ratio guide in your app so art doesn’t stretch during edits.

How Big Is 11×17 Paper? Size Compared

Compared with the ISO system, 11×17 sits near A3. A3 measures 297 × 420 mm (about 11.7 × 16.5 inches), so it’s a touch shorter and a little wider than ANSI B. That small mismatch matters when you swap templates or try to print an A3 layout on 11×17 without scaling, since the aspect ratios differ. That’s why an A3 poster dropped into an 11×17 frame can show tiny white edges unless you scale or extend the background.

• Near-match to A3 — Expect slim gaps or trims when you place an A3 design on 11×17 or the other way around.
• Half-step logic — Two Letter pages make one 11×17; two 11×17 sheets make one ANSI C (17 × 22).
• Aspect ratio shift — The ANSI series alternates ratios as you step up, so perfect 1:√2 scaling doesn’t apply.

How Large Is 11×17 Paper For Printing

Designers, office admins, and teachers use this sheet for compact posters, menus, seating charts, process maps, and engineering sketches. Folded once along the 17-inch edge, 11×17 becomes 8.5 × 11, which lets you make simple half-fold booklets on a copier. That half-fold is handy for proofs, church bulletins, handouts, and z-fold mailers.

• Pick the orientation — Use Tabloid (portrait) for tall posters or menus; use Ledger (landscape) for spreadsheets, schedules, and multi-column layouts.
• Match the series — If a client sends an A3 file, expect minor scaling or reflow on 11×17 because the aspect ratios don’t match.
• Mind the margins — Many office printers reserve 0.2–0.25 in on each edge. Bleed to the edge only on devices that support borderless printing.
• Plan a fold — For booklets, place page 4 and page 1 on the front, page 2 and page 3 on the back, then saddle-staple down the centre.

Names, Standards, And Aspect Ratio

The ANSI/ASME Y14.1 drawing sheet system defines a family that includes Letter (ANSI A), 11×17 (ANSI B), and larger engineering sizes. The set halves cleanly: two Letter sheets equal one 11×17; two 11×17 equal one 17 × 22 (ANSI C). Unlike ISO A-series pages, the width-to-height ratio alternates, so artwork doesn’t scale perfectly between every step. In print shops you’ll also hear “Tabloid” and “Ledger” for the same 11×17 sheet, with the name often tied to orientation.

Why A3 Isn’t Identical

The ISO A-series uses a constant 1:√2 ratio, which keeps scaling tidy. A3 is the closest match to 11×17, but not identical. When you must swap formats, adjust margins or scale by a few percent rather than forcing a hard fit that crops content.

11×17 Specs You Can Use

Quick check: Here are the working dimensions and a ready-to-use pixel target for crisp prints.

Size (in)	Size (mm)	Pixels @ 300 dpi
11 × 17	279.4 × 431.8	3300 × 5100

Need other targets? At 150 dpi, a quick office print needs 1650 × 2550 pixels. At 600 dpi for a line-art proof, prepare 6600 × 10200 pixels. Vector logos and type sit outside this math, since paths scale cleanly without adding pixels.

For large-view posters that hang a bit farther away, 240 dpi still looks clean. At 240 dpi, target 2640 × 4080 pixels. If you’re placing a photo inside a layout, scale images inside your design tool rather than stretching them on press. Use Bleed at 0.125 in (3.175 mm) when art runs to the edge.

• Export PDFs smartly — Embed fonts, flatten overprints, and keep the artboard at 11 × 17 with bleed added outside the trim.
• Set safe area — Keep text at least 0.25 in from the trim on all sides to avoid nicked edges.
• Choose stock — 24–32 lb bond (90–120 gsm) works for office prints; 80–100 lb cover (215–270 gsm) suits menus and mini-posters.
• Proof at scale — If your printer can’t run 11×17, tile a proof or output a reduced-scale print with a ruler check box.

Practical Setup And Troubleshooting

Software Presets

Quick start: Here are clean presets for common tools so your export matches the press run.

• Adobe Illustrator — New document → Size: 11 × 17 in → Bleed: 0.125 in all sides → Color: CMYK → Raster Effects: 300 ppi.
• Adobe InDesign — Intent: Print → Page Size: 11 × 17 in → Facing Pages: on for booklets → Margins: 0.5 in → Bleed: 0.125 in.
• Affinity Publisher — Document Setup → Page: 11 × 17 in → DPI: 300 → Colour Format: CMYK/8 → Bleed: 0.125 in.
• Microsoft Word — Layout → Size → Tabloid 11 × 17 → Margins: 0.5 in → Check printer supports the size.
• Google Docs — File → Page setup → Paper size: Tabloid → Set custom margins; device must accept the size.

Troubleshooting

Quick fixes: When things look off, these checks often solve it without a service call.

• Wrong rotation — If content flips, pick “Tabloid” vs “Ledger” in the driver and set the right flip edge for duplex.
• Clipped borders — If colour stops short of the edge, add 0.125 in bleed and export with crop marks.
• Soft graphics — Replace low-pixel images with files that meet the 3300 × 5100 target or import vectors.
• Banding — Switch to a different screen angle or print on a thicker coated stock that holds toner evenly.
• Colour shift — Turn off RGB black; use rich black (C60 M40 Y40 K100) for solids and a neutral CMY mix for tints.
• Mixed page sizes — If a PDF mixes Letter and 11×17, use “Fit paper to size” off and print a range per size.
• Wrong tray picks — Lock the driver to the tray that holds 11×17 so a busy device doesn’t pull Letter by mistake.
• Hairline gaps — Expand background boxes by 0.01 in to hide hairlines caused by flattening on old drivers.

Printing, Folding, Mailing, And Cost

In office channels you’ll find 11×17 in reams of 500 sheets, usually 24–28 lb bond for everyday use. Print shops will stock heavier 80–100 lb cover for menus and mini-posters. Coated options lift photo contrast and resist fingerprints; uncoated reads softer for text-heavy handouts. Ask for FSC or recycled stocks if sustainability targets matter to your team.

• Ask for cut-size — “11 × 17 cut-size” fits copier trays; parent sheets are larger and trimmed in-house.
• Match whiteness — Mixed stocks in the same project can shift colour; buy from one mill for a uniform look.
• Order overage — Add 5–10 sheets for setup and test runs so you don’t stall mid-print.

Office copiers that support 11×17 usually label trays as “11×17,” “Tabloid,” or “Ledger.” If you print borderless, confirm the device can actually bleed; many laser devices leave a slim unprintable edge. For folded pieces, score heavier cover stocks before the fold to prevent cracking. When you mail, 11×17 can move as a flat or fold down to Letter in half; check current postal guidelines for weight and thickness brackets.

For mail, most postal services place 11×17 flats in a pricing tier based on weight and thickness. A single 24 lb bond sheet mailed flat usually stays under standard flat limits. Heavier cover stocks or multi-sheet inserts can move the piece into a higher tier, so weigh a finished sample before you buy postage.

• Load the tray — Set the guides tight to avoid skew; pick the matching size in the print driver.
• Pick duplex correctly — On a landscape spreadsheet, “flip on short edge” keeps page order intact.
• Mind toner coverage — Heavy solids on cheap stock can curl; use a lighter tint or switch to coated cover.
• Test a single sheet — Run one print, fold it, and check panel alignments before committing to a stack.

The sheet is big enough for posters and charts, small enough for desktop devices, and flexible for quick folds. Now you know the working size, close ISO match, pixel targets, and layout moves that keep prints clean. If you keep templates handy and export with bleed and safe area in place, you’ll get dependable results from any shop that handles ANSI B.
