Outdoor 3x5 custom printed rectangular flag with Ridgeline Athletics invent branding, white hoist header and brass grommets on a pole at an event entrance

If you are locking artwork for an event, storefront pole, or stadium spirit run before you send a quote, custom flag sizes decide whether the fabric reads from the curb—or disappears against the building. This guide sticks to live quote-form options on iPopupbanner’s custom printed flags page: rectangles from 12×18 in through 6×10 ft, Single Sided Reverse vs Double Sided 3 Layers, and grommet / pole-sleeve finishes. Specs below come from that PDP only—no invented prices, MOQ claims beyond what the page states, or review counts.

Outdoor 3x5 custom printed rectangular flag with Ridgeline Athletics invent branding, white hoist header and brass grommets on a pole at an event entrance
Invent scene brand “Ridgeline Athletics” on a soft landscape rectangle (fly/hoist ≈ 1.67 for a 3×5). Live finishes include brass grommets and/or pole sleeves—not a feather or teardrop silhouette.

Custom flag sizes on the live PDP (12×18 in to 6×10 ft)

Suppliers label “3×5” differently. For RFQs on iPopupbanner custom printed flags, use these rectangles from the live quote form and FAQ:

  • 12In × 18In — small indoor / accent flag
  • 2Ft × 3Ft
  • 3Ft × 5Ft — common outdoor / event workhorse
  • 4Ft × 6Ft
  • 5Ft × 8Ft
  • 6Ft × 10Ft — large outdoor display
  • Customize size — free-text when your site needs a non-chart footprint

The official size chart labels the same physical flags as fly (width) × hoist (height): 18×12 in, 3×2, 5×3, 6×4, 8×5, and 10×6 ft. Chart aspects sit around 1.50–1.67—wide landscape rectangles, not near-square posters. When you write the purchase order, pick one form size (or customize) so the proof matches the pole or fence span you actually have.

Single Sided Reverse vs Double Sided 3 Layers

The quote form Print Type offers two constructions that change how the back reads in traffic:

  • Single Sided Reverse — one-layer flag; the page states 70–95% bleed on the reverse as standard (FAQ also cites about 80%). The back shows a reverse image—lighter, but usable for one-way traffic (busy road, train stop).
  • Double Sided 3 Layers — two printed faces sewn with a middle 100% blackout layer so art reads correctly from both sides. Heavier; needs more wind to fly. Strong when traffic moves slowly (sidewalk, city avenue) or you need different front/back messages—page states different front/back designs on DS at no extra cost.

FAQ nuance to keep in mind: lightweight SS flies easily in low wind; DS lasts longer in windy use but is heavier. Pick from the real traffic pattern—not from a stock photo.

Live PDP options: Single Sided Reverse (one-layer reverse bleed) vs Double Sided 3 Layers (blackout middle). Choose from traffic speed and whether both sides must read correct.

Grommets vs pole sleeves (finish matrix)

Finishing options on the live form (spelling on page includes “Gromments”):

  • Only Sleeve Left
  • Left Sleeve with Gromments
  • Only Sleeve Top
  • Top Sleeve with Gromments
  • 4 Corner Gromments
  • None Sleeve and Gromments

Body copy highlights rust-free brass grommets and a strengthened canvas header with double-stitched edges. Default sleeve is designed to fit 1.25-inch poles; other sleeve diameters need a note on the order. Install methods named on page: cords, strings, bungees, cable ties, or screws and washers through grommets on a solid wall. Pole pockets help indoor hanging when selected. FAQ: fabric banners are stitched around the perimeter with 3 layers for grommet strength; double-stitch hems about ½″ wide.

Poles: one FAQ states the company does not sell flag poles; another says mounting rings/poles may be purchased separately. Do not assume poles ship in the standard flag order—confirm accessories on your RFQ if you need hardware.

Materials, print, indoor / outdoor use

Claims you can verify on the live custom flags page:

  • Durable polyester with dye sublimation printing; digital print with no color restrictions called out on page
  • UV-protected inks that resist sun but are not completely UV-proof
  • Recommended for indoor or outdoor use; bring flags in at night and in bad weather to prolong life; do not leave banners out in extreme weather
  • Canvas header + double-stitched edges; vinyl-coated polyester mentioned in the why-buy block for fade resistance

These are rectangular fabric flags—not feather/teardrop pole sets and not pop-up A-frames. For tall blade/teardrop curb markers, compare feather flags or teardrop flags instead.

Buyer checklist before you hit inquire

  1. Pole / fence / wall span → pick 12×18 / 2×3 / 3×5 / 4×6 / 5×8 / 6×10 (or customize).
  2. Traffic speed and both-side read → Single Sided Reverse or Double Sided 3 Layers.
  3. Mount method → grommets, sleeve, sleeve+grommets, 4-corner, or none—from the live finish list.
  4. Indoor vs outdoor exposure → plan take-down in bad weather; UV inks resist but do not stop fade forever.
  5. Send logo / sketch → free design proof → approve → PayPal → production and free shipping window.

Next step: open the custom printed flags quote form, lock size + print face + finish, and request a free design proof before you commit artwork.

FAQ

What custom flag sizes can I order on iPopupbanner?

Live quote form and FAQ list 12×18 inches, 2×3, 3×5, 4×6, 5×8, and 6×10 feet, plus a customize-size field. The size chart shows the same rectangles as fly×hoist (18×12 in through 10×6 ft).

Should I order Single Sided Reverse or Double Sided 3 Layers?

Choose Single Sided Reverse for lighter fly and reverse bleed on the back (about 70–95% / ~80% on page). Choose Double Sided 3 Layers when both sides must read correct with a blackout middle—heavier, better for slower traffic or dual messages.

Do custom printed flags include poles?

Do not assume poles are in the standard flag order. One FAQ says poles are not sold; another mentions accessories such as mounting rings and poles available separately. Confirm hardware on your RFQ.

Is there a minimum order quantity?

The live page states No MOQ—design and buy 1 or 1,000. Free design and free shipping windows (5 to 12 days stated) are also on-page.
