A custom boat flag runs anywhere from $50 to $135 depending on size and whether you print one side or both, and that range surprises a lot of first-time buyers who expected a flat rate. Whether you’re flying a burgee with your boat name, a signal flag for a fishing tournament, or a novelty flag off the flybridge, the price and turnaround depend on a handful of specs you can pin down before you request a quote: size, sides, fabric, and how fast you actually need it on the halyard.
This guide walks through what custom boat flags cost at real vendors, how nylon and polyester compare for saltwater use, and how long production realistically takes — so a “10-15 business days” lead time doesn’t catch you off guard three days before you leave the dock for a regatta.

What custom boat flags cost by size
Real per-flag pricing is hard to find because most sites gate it behind a quote form, but Gettysburg Flag Works publishes rates for its full-color custom boat flag line, and they’re a useful benchmark for what to expect elsewhere. A 12×18 inch flag printed on one side runs $50, while the same size printed so the design reads correctly on both sides — rather than showing a mirror image — costs $70. Step up to 16×24 inches and the gap widens: $75 single-sided versus $135 double-sided.
That roughly-doubles-the-price pattern for double siding holds across the industry, because a true double-sided flag isn’t just printed twice — it’s two panels sewn together so there’s no bleed-through or mirroring, which adds both material and labor. Across vendors more broadly, a basic polyester flag in a small size typically lands in the $30-$80 range, with premium nylon, double-sided construction, or a custom shape pushing $150-$250 or more. If a quote comes in well outside that band, ask what’s driving the difference — it’s usually panel construction, denier weight, or a rush fee.
Single-sided vs. double-sided: which you actually need
A single-sided flag — often listed as “single reverse” — is printed once, then constructed so the reverse shows a mirror image of the design rather than a blank or bled-through panel. That’s the standard choice for text-heavy designs like a boat name, hailing port, or yacht club burgee, because the words still read correctly from either side, just flipped. Most boaters flying a name flag or burgee pick this option since it runs 25-30% cheaper and holds up just as long in normal use.
Double-sided construction earns its higher price when the artwork includes fine detail, a photo, or asymmetric elements that would look wrong mirrored — a specific logo lockup, an off-center mascot, or a flag meant to read identically from the dock and from the water. If your design is centered and symmetrical, which most burgees are, single reverse saves money without anyone noticing a difference from either angle.
Nylon vs. polyester for a boat flag
Nylon and polyester are the two fabrics you’ll be offered, and the difference matters more on a boat than almost anywhere else a flag flies. 200-denier nylon is lighter and catches a breeze at lower wind speeds, which helps if you’re often anchored or motoring slowly and want the flag to actually fly instead of hang limp. It also takes dye more vividly, so colors read brighter and more saturated.
Polyester is heavier and denser, making it the better choice in sustained higher wind and constant salt spray — boats that are underway often or moored in open water tend toward polyester for that reason. It’s usually the less expensive option too, and what most digital-print shops default to unless you specify nylon. Neither fabric is wrong for a boat flag; the choice comes down to typical wind conditions and how much color vibrancy matters for your design. Split time between calm coves and open chop? Polyester is the safer all-around pick.
How far ahead to order custom boat flags
Lead time is where custom boat flag orders most often go sideways for people planning around a launch date, a delivery, or a tournament. None of the major flag printers ship same day — even the fastest standard turnaround among named vendors is several business days, and that clock doesn’t start until you’ve approved a digital proof, which can itself take 24-48 hours to arrive.
Add shipping on top of production and a straightforward custom flag order can take two to three weeks door to door. If you’re working toward a specific date — a christening, a tournament, a holiday cruise — request the proof immediately after submitting artwork and ask about rush production up front; shops that offer it usually charge a flat fee rather than pricing it per flag.
| Vendor | Standard lead time | Rush option |
|---|---|---|
| Gettysburg Flag Works | 10-15 business days after art approval | Available by phone request |
| BestFlag.com | 4 business days (orders up to 25 flags) | 2-4 business days after proof approval |
| North Star Flags | 6-8 business days | Not specified on site |
| Green Valley Flags | 24-48 hr proof, plus 5 production days, plus ~5 days shipping | Rush options available |
Sizing your flag to your boat
Boat flag sizing follows a rule of thumb tied to your vessel’s overall length, not personal preference: the flag’s fly length (the long horizontal edge) should run roughly five-eighths of an inch for every foot of boat length, with the hoist (vertical edge) at about two-thirds of the fly. In practice that works out to a 12×18 inch flag for boats under about 20 feet, 16×24 for the 20-34 foot range, and 20×30 or 24×36 for anything larger or for a flag flown from a taller staff where visibility from a distance matters.
Oversizing isn’t just cosmetic — a flag too large for its staff catches more load in wind and wears out its grommets or sleeve faster than one sized correctly. When in doubt, size to the staff you’re mounting it on, not just the length of the boat.
Placing the Order
Most printers, including every vendor referenced here, will produce a single custom boat flag — there’s no minimum order quantity for digitally printed flags, since the process doesn’t require a screen or die setup. That said, per-flag cost drops meaningfully at volume: expect the first price break around 3-6 units, with deeper discounts at 12, 25, 50, and 100, which matters if you’re outfitting a whole marina slip row or a fleet for a club event.
Before submitting artwork, confirm three things with whoever’s printing it: whether they need a vector file (AI, EPS, or a high-resolution PDF) or can work from a photo, whether they match Pantone (PMS) colors or eyeball it from a screen, and whether the flag ships with brass grommets, a canvas heading with grommets, or a pole sleeve — your mounting hardware needs to match what arrives.
Frequently asked questions
Is there a minimum order for custom boat flags?
No. Because custom boat flags are digitally printed rather than screen printed, most shops — including Gettysburg Flag Works, BestFlag, and Fest Flags — will produce a single flag with no setup fee. Volume pricing kicks in if you’re ordering a batch, but one flag is a normal order.
How much does a custom boat flag cost?
Based on published pricing from Gettysburg Flag Works, a 12×18″ flag runs $50 single-sided or $70 double-sided, and a 16×24″ flag runs $75 single-sided or $135 double-sided. Larger sizes, nylon fabric, or a custom shape push the price toward $150-$250+ at other vendors.
Should I choose nylon or polyester for a boat flag?
Nylon is lighter, flies in lighter wind, and shows more vivid color, but costs more. Polyester is heavier, holds up better in sustained wind and constant salt spray, and is usually the less expensive default at most print shops. Choose based on your typical wind conditions.
How long does it take to get a custom boat flag made?
Standard production alone runs 10-15 business days at Gettysburg Flag Works and 6-8 business days at North Star Flags, and that clock starts only after you approve a digital proof, which can take 24-48 hours to receive. Plan on two to three weeks total including shipping, and ask about rush options if you’re working against a date.
What size boat flag do I need?
A common rule of thumb is 5/8 inch of flag length for every foot of boat length. That puts most boats under 20 feet at a 12×18″ flag, 20-34 foot boats at 16×24″, and larger boats or taller staffs at 20×30″ or 24×36″.
Will people see my design correctly from both sides of the boat?
With a single-sided (single reverse) flag, yes — the design is constructed so it reads correctly from either side, just mirrored, which works fine for text and centered logos. Only asymmetric artwork or photos need true double-sided construction to avoid looking backwards from one angle.
The bottom line
A custom boat flag is a small purchase with a lot of hidden variables — size relative to your boat, single versus double print, nylon versus polyester, and a production window that’s longer than most people assume. Nail those four specs before requesting a quote and you’ll get an accurate price on the first call instead of a range. Budget $50-$135 for a straightforward single flag in a common size, plan on two to three weeks door to door, and treat a rush fee as a backup plan rather than the default.
