Poster Board 22×28”, 400gsm Large Thick Heavyweight Cardstock
The DBBNTB Poster Board is a pure pulp-based, double-sided white poster board designed for heavy-duty use in classrooms, offices, and home studios. With 400 gsm thickness, it resists wrinkling and ink bleed, offering a substantial feel for signs, DIY crafts, and displays. Best for projects that require durability and long-lasting color retention. Limitations include limited color options beyond white and a heavier weight for very small craft spaces. Suitable for signs, scrapbooks, and event displays where reliability matters.
Pacon Super Value Poster Board, 22″ x 28″
These boards offer economical value with bright white, uncoated surfaces ideal for posters, signs, and crafts. They’re best for budget-conscious classrooms or basic presentations where quick-turnaround projects are common. A limitation is that they may not be as rigid as heavier options, which can affect very large or multi-day displays.
Corrugated Plastic Sheet 24×36” (Pack of 2)
Durable plastic sheets suitable for indoor and outdoor use. They are waterproof and light, making them ideal for weather-resistant signage and long-lasting displays. Best for projects requiring weather resistance, though they may be less ideal for heavy ink applications and multi-layer mounting due to plastic surface properties.
Hixdo Foam Board 24×36” 6mm Thick
Hixdo foam boards offer lightweight rigidity with a 6mm core and plastic edge protection. They perform well for lightweight artwork, presentations, and portable displays. Choose this if you need easy cutting and portability; avoid if you require heavy ink absorption or archival storage due to foam materials.
DBNBTUP 24×36” Heavyweight Poster Board, 25 Sheets
This heavyweight poster board mirrors the 22×28 version with a larger 24×36″ footprint and double-sided white finish (glossy on one side, matte on the other). It’s best for large posters, signage, and displays that demand a sturdy, durable surface capable of handling multiple materials. The larger size may require more cutting and storage space, which is a consideration for smaller work areas.
Buying Guide
What material should you choose for heavy duty poster boards?
- Paper/cardboard boards (like 400 gsm) are sturdy and provide clean color reproduction. They are best for indoor signs, school projects, and long-lasting displays when ink bleed resistance is important.
- Foam boards are lighter and easy to cut, ideal for quick demonstrations and portable exhibits, but may not absorb heavy ink or paints as well as pulp-based boards.
- Corrugated plastic boards excel for outdoor or weather-exposed signage and very durable signs, but may have a slick surface that affects certain media adhesion.
Which size fits your needs?
- 22×28″ boards are common for classroom posters and mid-sized displays; they balance portability with surface area.
- 24×36″ boards offer a larger surface for banners, signage, and event backdrops but require more storage space and cutting precision.
What about double-sided surfaces?
- Double-sided white boards (glossy/matte) give flexibility for different media and effects. They reduce the need for back-to-back printing and can save time during classroom or event setups.
- Single-sided boards may suffice for simple signs or one-sided art, especially when cost is a priority.
Practical tips
- Cut with ordinary scissors or a craft knife for clean edges, especially on thicker boards.
- Test ink and markers on a small area to confirm bleed resistance and drying times.
- Consider a protective backing or storage solution to prevent warping when not in use.
