A standard garden flag measures 12 × 18 inches and hangs from a sleeve across its top, on a small stand pushed into the ground.
- Retail variants: some retailers list it as 12.5 × 18 inches
- At Senior Flags: 30 × 45 cm, which is 11.8 × 17.7 inches
- House flags: usually about 28 × 40 inches; some house banners are 28 × 44 inches
- Our house flag: 70 × 100 cm for the 28 × 40 size

Shanghai Senior Flag Manufacture Co., Ltd. was founded in 2003 and makes its flags at its factory in Lu’an, Anhui, where printing, cutting, sewing, quality control and packing are done in-house. Our custom garden flags come in a standard 30 × 45 cm size supplied with a 1 m metal stand, a larger 70 × 100 cm size, and custom sizes. They are made from double-layer 300D polyester or 300D Oxford fabric and printed by double-sided digital printing or silk screen, from a minimum of 100 flags.

What sizes do garden flags come in?
The same small flag is sold under slightly different sizes, most commonly 12 × 18 inches. Heartland Flags gives 12 × 18 inches as the most common size and calls a half-inch difference normal. Flags R Us lists garden flags at about 12.5 × 18 inches, banner garden flags at about 12.5 × 28, house flags at about 28 × 40 and estate flags at about 36 × 54. Elmer’s Flag & Banner mentions 28 × 44 inch house banners, and The Flag and Sign Place also lists 12 × 17 inch garden flags and 28 × 42 inch medium flags. The table puts those retail sizes next to the metric size a factory sews.

Inch sizes as listed by US retailers; centimeters converted at 2.54 cm per inch.

Sizes are usually written width first (Heartland Flags describes the format as width by height), so a garden flag described as 30 × 45 cm is 30 cm across the sleeve and 45 cm from top to bottom. Some charts put the height first, so name each side on your order: “30 cm across the sleeve, 45 cm drop.” Also say whether the size includes the top sleeve, because Heartland Flags notes that makers differ on this.
Why is 30 × 45 cm not exactly 12 × 18 inches?
Twelve inches is 30.48 cm and eighteen inches is 45.72 cm. A flag made at 30 × 45 cm is about half a centimeter narrower and three quarters of a centimeter shorter than the inch size on the label. Pole flags have the same gap, where 90 × 150 cm is sold as 3 × 5 ft; our standard flag size chart gives every pole-flag size in feet and centimeters.
The same arithmetic tells you which label to use. A 30 × 45 cm flag is 0.48 cm (0.19 in) narrower than 12 inches, well inside the half-inch width difference that Heartland Flags says typically fits a standard holder. Against a 12.5 × 18 in listing it is 1.75 cm (0.69 in) narrower, more than that half inch, so list a 30 × 45 cm flag as 12 × 18 in, not 12.5 × 18 in. Our 70 × 100 cm flag is 1.12 cm narrower and 1.6 cm shorter than 28 × 40 in, but 11.8 cm shorter than a 28 × 44 in house banner, so it should not be sold as a 28 × 44.
Heartland Flags treats gaps of this size as normal. It notes that many standard holders have an arm around 12 to 13 inches wide and that a half-inch difference in width typically fits. Our 1 m stand is made for the 30 × 45 cm flag. If the flag will go on another stand, or you need an exact inch size, ask for the size tolerance to be written on the quotation.
If you sell into the US, describe the product the way customers search (“12 × 18 in garden flag”) and give the exact metric size in the specification, so a customer who measures the flag sees what you promised.
If you already stock stands from another supplier, measure both the length of the horizontal arm and its thickness and send them with your inquiry. The sleeve opening has to take the arm’s thickness: Heartland Flags warns that if the sleeve is too tight, forcing it onto a thicker arm can stress the stitching.
Which size do you need: a garden flag or a house flag?
A 30 × 45 cm garden flag goes on a small ground stand or a mailbox post; a 70 × 100 cm house flag goes on a pole in a wall bracket.
| Garden flag | House flag | |
|---|---|---|
| Size | 30 × 45 cm (12 × 18 in) | 70 × 100 cm (28 × 40 in) |
| Mounts on | A small ground stand or a mailbox post | A pole of about 60 in on a wall bracket |
| Suits | Flower beds, walkways and entry gardens | A front porch or a broad exterior wall |
| Our hardware | 1 m metal stand, supplied with the flag | Confirmed at quotation; see our wall-mounted flagpole kits |
Our 1 m stand is designed for the 30 × 45 cm flag, and other flag sizes are confirmed with the quotation. For the 70 × 100 cm size, ask which pole fits when you order: our wall-mounted flagpole kits have the pole length confirmed for the flag size at quotation, from 20 pieces. In the US, The Flag and Sign Place says most of the poles and brackets it carries are 1 inch in diameter, with 3/4 inch and 1 3/8 inch poles also available, so send the diameter of the pole the flag will hang on.

How do the garden flag stand and the flag fit together?
The metal garden flag pole supplied with our 30 × 45 cm flag is 1 m high and is assembled by hand from these parts:
- A horizontal top arm, which the flag’s top sleeve slides onto.
- Pole sections that join together by hand, with no tools.
- A lower section that ends in a ground stake, for lawns, flower beds and planters.
A stopper clip helps keep the flag in position on the arm. The pole is also sold on its own for retailers who already source their own 30 × 45 cm garden flags: the minimum is 100 pieces, packed one to a polybag and 100 to an export carton.
Should a garden flag be printed on one side or both?
A garden flag is often seen from the house as well as from the street. Heartland Flags recommends two panels sewn together when words must read correctly from either direction, and notes that this style can be slightly heavier and cost more. Our garden flags use double-layer 300D fabric with the layers stitched together, so the design can be printed and displayed on both sides. If text must read correctly from both sides, say so on your order and check both faces when you confirm the artwork. Single-sided printing is available when the design only needs to be shown on one side.

Ordering garden flags in several designs? Send the artwork for each design with the quantity per design. We reply with a quotation for the flags and stands, and the sample time.
What should a wholesale garden flag order include?
A wholesale garden flag order should state the finished size, stand, sides, fabric, printing, quantity per design and packing.
Before bulk production, each order goes through four checks at our factory: artwork review, specification review (size, material and quantity), production feasibility and pre-production confirmation. Finished flags, quantities and packing are checked again before shipment.
Send these details with your inquiry so we can quote flags and stands together:
| Item | What to state | Why it matters |
|---|---|---|
| Finished size | 30 × 45 cm, 70 × 100 cm or your size, width first, and whether it includes the sleeve | Sets fabric use and the stand |
| Stand | With our 1 m stand (the 30 × 45 cm flag is supplied as a set), or the length and thickness of your own stand’s arm; for 70 × 100 cm, the diameter of the pole | The sleeve has to fit the arm’s thickness |
| Sides | Printed on both sides or one | Single-sided printing is available when the design only needs to be shown on one side |
| Fabric | Double-layer 300D polyester or 300D Oxford | Ask for the fabric weight in g/m² on the quotation |
| Printing | Double-sided digital or silk screen | Chosen by the artwork and the quantity |
| Quantity | From 100 flags | List the quantity of each design, and ask how several designs count toward the minimum |
| Packing | One flag-and-stand set per bag, 250 sets per export carton | Other packing is confirmed on the quotation |
For the fabrics themselves, the flag fabric guide compares 300D with the lighter polyesters. Minimums and payment terms by product are in custom flag MOQ and lead times.
How long do custom garden flags take?
Custom garden flags take 5 to 7 calendar days for a sample and 15 to 20 for bulk, counted from artwork confirmation. Count back from the date the flags must be in your warehouse:
| Stage | Time | Counted from |
|---|---|---|
| Sample | 5 to 7 calendar days | Artwork confirmation |
| Bulk garden flags | 15 to 20 calendar days | Artwork confirmation |
| Metal stands | 20 to 25 calendar days | Artwork confirmation |
| Shipping | Depends on route | Not included above |
Calendar days from artwork confirmation, excluding shipping.
For example, if flag-and-stand sets must be ready to ship on 30 April, confirm the artwork by 5 April at the latest, because stands take up to 25 days. Flags without stands, at up to 20 days, need confirmed artwork by 10 April. Add the shipping time on top. If you want to approve a sample before bulk production starts, ask how that changes the bulk date.
Frequently asked questions
What size is a standard garden flag?
12 × 18 inches in US retail, and some sellers list 12.5 × 18 inches. We make it as 30 × 45 cm, which is 11.8 × 17.7 inches.
Are all garden flags the same size?
No. The standard size varies by about half an inch between sellers, and there are larger formats: banner garden flags of about 12.5 × 28 inches and house flags of about 28 × 40 inches. Check the sleeve against the stand arm before ordering in volume.
What is the size of a small garden flag?
The name is used two ways. Flags R Us sells 6 × 13 inch mini flags for window boxes and plant pots, but both Flags R Us and Heartland Flags also use “mini flag” as another name for the 12 × 18 inch garden flag. Check the inches on the listing, not the name.
How do you know which flag size to buy?
Go by the hardware. A garden flag goes on a small ground stand or mailbox post; a house flag of about 28 × 40 inches hangs from a pole of about 60 inches on a wall bracket.
What size is a house flag?
About 28 × 40 inches, with some house banners at 28 × 44 inches. We make the 28 × 40 size as 70 × 100 cm.
Does a 12 × 18 inch size include the sleeve?
It depends on the maker. State on your order whether the finished size includes the top sleeve.
