Cardstock weight is the single most important factor in how your project feels in-hand. At 300 GSM (equivalent to 110 lb. cover weight), this paper is the tipping point between flimsy office paper and rigid board stock. It provides the substantial, professional stiffness required for high-end invitations, durable business cards, sturdy photo mats, and serious craft projects without the bulk of a full chipboard.
I’m Min — the co-founder and writer behind Gadgets Feed. I have spent countless hours analyzing technical specifications, comparing sheet counts, and cross-referencing real customer feedback across dozens of cardstock brands to find the absolute best options in this precise weight class.
Whether you are printing wedding invites at home, building a handmade card base, or creating a thick media for a mixed-media art piece, finding the right sheet can be tricky. This guide breaks down the specific options to help you find the perfect 300 gsm cardstock for your exact project, from budget-friendly bulk packs to premium black-core sheets.
How To Choose The Best 300 GSM Cardstock
While the weight is standardized, not all 300 GSM cardstock is created equal. Your choice should be driven by three specific factors: the color and finish of the paper, the sheet count for your project size, and the thickness tolerance of your printer. This weight is substantial — many standard home printers will struggle to feed it without jamming.
Color and Core Integrity
The most common mistake is buying white cardstock when you need a vibrant black or a rustic kraft brown. For black cardstock, you specifically want a “solid-core” sheet where the color runs all the way through. This prevents an ugly white edge from showing when you fold, cut, or tear the paper. For white cardstock, look for a high “brightness” rating (around 98), which ensures that your colors pop with contrast.
Sheet Count and Value
300 GSM cardstock is expensive per sheet compared to standard paper. When comparing products, look at the sheet count versus the price. A bulk pack of 200 sheets of 5×7 cardstock might offer a better per-sheet cost for invitation printing than a pack of 100 letter-size sheets. However, if you only need a small batch for a specific project, a 60-sheet pack saves you money and storage space.
Printer Compatibility and Feed Mechanism
This is the most critical technical detail. A printer with a “straight paper path” (usually a rear manual feed slot) will handle 300 GSM far better than a printer that bends paper around a tight roller. If your printer has a standard U-shaped feed path, you may need to hand-feed each sheet individually. Always check your printer’s manual for the maximum paper weight it supports in the covers and cardstock settings.

In‑Depth Reviews
1. Desktop Publishing Supplies White 110lb Cover Cardstock
This cardstock from Desktop Publishing Supplies sets the benchmark for professional-grade white paper at 300 GSM. The 98 brightness rating means your text and graphics appear with maximum contrast, making it the ideal choice for restaurant menus, business brochures, and high-end wedding invitations where color accuracy and sharpness are non-negotiable.
The smooth finish is designed for jam-free feeding through manual feed trays on both laser and inkjet printers. Users report that while you might need to gently guide the lead sheet into a printer like the Canon Pixma MX490, the print results are crisp with no feathering or bleeding, particularly on text-heavy layouts.
It scores and folds very cleanly when a bone folder is used, which prevents fiber lift on dark printed areas. The 100-sheet count offers a solid balance for small businesses or frequent crafters. Note that shipping packaging can sometimes cause corner damage to the top sheets — a minor risk for such a thick, premium paper.
Why it’s great
- 98 brightness delivers sharp, professional-quality printing.
- Scores and folds cleanly with minimal fiber lift.
- Works with manual feed on inkjet/laser printers.
Good to know
- Top sheets may suffer corner damage during shipping.
- Requires manual feeding; will not work in bypass dump trays.
2. COLOANDUS Heavyweight Black Cardstock
For projects requiring a true, rich black that doesn’t reveal a white edge when cut or folded, the COLOANDUS solid-core cardstock is the definitive choice. At 0.35mm thick, this 300 GSM sheet provides the structural rigidity needed for premium handmade card bases, scrapbooking layers, and die-cut shapes.
The “solid-core” construction means the black dye penetrates completely through the paper fiber. This is critical for laser-cut projects, where any light hitting the edge reveals the material’s integrity. Reviewers specifically note that it cuts and engraves beautifully on CO2 laser cutters for earring cards and intricate stencils.
Beware that the thickness will challenge most standard home printers. You will need to hand-feed it using a straight paper path printer. It is best used as a construction material or for print-on-demand services rather than high-volume home printing.
Why it’s great
- True solid-core black; no white edges on cuts or folds.
- Excellent for laser engraving and die-cutting.
- Very rigid; holds shape well for card bases.
Good to know
- Will likely jam in standard U-path printers.
- Not suitable for high-volume home printing.
3. TownStix Brown Kraft Cardstock 300 GSM
If your project demands an organic, handmade aesthetic, the TownStix Brown Kraft cardstock delivers a warm, earthy base that stands apart from stark white paper. The matte surface is particularly well-suited for drawing, calligraphy, and dry media applications where you want the paper tooth to grab the medium.
This 100-sheet pack of letter-size paper is incredibly stiff — users note that holding a single sheet horizontally results in almost no sag. This makes it an exceptional choice for notebook covers (like crafting a custom Midori Traveler’s Notebook insert) and for 3D structural projects that require self-supporting panels.
It cuts cleanly with a laser engraver for applications like jewelry cards. However, due to its density, you will need a dedicated craft blade for scissors or a die-cutting machine, as it can dull standard blades quickly. It is not recommended for standard inkjet printers due to a high jam rate.
Why it’s great
- Extremely rigid; holds weight without bending.
- Ideal for laser engraving and notebook covers.
- Warm kraft color perfect for rustic crafts.
Good to know
- Not compatible with most standard home printers.
- Thickness can dull craft blades faster.
4. PENPRIS White Blank Cards 5×7
The PENPRIS pack of 200 pre-cut 5×7 blanks is the ultimate volume play for invitation suites and greeting card runs. Because the sheets are pre-cut to size, you eliminate the need to trim down larger stock, saving significant project time. The 300 GSM weight gives each card a substantial, heirloom-quality feel.
Crafted from acid-free materials, these cards are designed for longevity, making them suitable for scrapbooking keepsakes or formal archival announcements. The texture is smooth enough for crisp inkjet and laser printing but has enough tooth for fountain pen writing without feathering.
Reviewers praise the pure white tone that doesn’t lean warm or cool. A small batch of users noted slight size inconsistencies that could be problematic for perfectly aligned notch-pad assembly. For general invitation printing and card making, the value-per-sheet ratio is very hard to beat.
Why it’s great
- Great per-sheet cost for a 200-count pack.
- Pre-cut to standard 5×7 format; no trimming needed.
- Acid-free for long-term archival projects.
Good to know
- Minor size variability reported in some batches.
- Not suitable for notepad assembly with perfect register.
5. Guakicae White Cardstock 5×7
The Guakicae 5×7 card stock is a reliable, general-purpose white cardstock that handles a wide range of wet media without bleeding. Users report that markers, watercolor paints, and gel pens rest on the surface without soaking through to the other side, making it an excellent blank canvas for mixed-media projects.
With 150 sheets, this pack sits in the value sweet spot between small trial packs and massive bulk boxes. The double-sided blank design allows for internal printing or drawing on both faces, which is useful for postcards or folded card inserts.
Quality control can be a minor factor — some users have reported receiving slightly fewer sheets than the advertised count, and a few edges arriving with scuff marks. For the price point, the paper thickness and structural rigidity are on par with more expensive brand-name stock, making it a solid choice for general DIY invites and handmade cards.
Why it’s great
- Handles watercolor and markers without bleed-through.
- Good value with 150 sheets in the pack.
- Bright white surface for vivid color printing.
Good to know
- Some packs arrive with fewer than 150 sheets.
- Edges can have minor scuffing from packaging.
6. TownStix Heavy White Cardstock 60 Sheets
The TownStix 60-sheet pack is the perfect entry point for those new to working with 300 GSM cardstock. It offers a low barrier to entry for testing the weight and thickness without a large financial commitment. Users consistently report that this paper feeds remarkably well through printers like the Epson ET-4850 for duplex printing.
Despite the lower price, the paper does not cut corners on stiffness. It holds up beautifully for high-stress projects like game card printing and photo matting. The white color is serviceable, though reviews note it is not the brightest white on the market — colors will print with slightly less pop than on a 98-brightness sheet.
This is a fantastic option for trial runs, classroom projects, or small batch card-making where quantity is not the priority. The 60-sheet count is perfect for a single focused project like a wedding RSVP card set.
Why it’s great
- Printer-friendly; works for duplex printing on Epson.
- Low-cost entry to test 300 GSM.
- Sturdy enough for photo matting and business cards.
Good to know
- White color is not ultra-bright for max contrast.
- Small sheet count; not for bulk runs.
7. TUXIYA Colored Cardstock 300 Sheets
The TUXIYA assortment offers the widest spectrum of color options in this roundup, featuring 50 different vibrant shades including fluorescent accents. This is the go-to pack for teachers, parents, and party planners who need a rainbow of hues for classroom displays, origami, and bunting decorations.
It is important to note that this cardstock is 180 GSM, not 300 GSM. While it is thicker than standard copy paper, it is much lighter than the other entries on this list. It will not provide the same structural rigidity for card bases or heavy 3D projects, but it is perfectly suited for general craft and school use where a wide color range is the priority.
The paper is solid-core dyed, meaning the color runs through the entire sheet — no white edges on tears. It prints well for full-background projects and is compatible with both laser and inkjet printers without jamming due to its lighter weight.
Why it’s great
- 50 vibrant colors in one economical pack.
- Solid-core dye; no white edges.
- Printer-friendly without jamming.
Good to know
- Weight is 180 GSM, not 300 GSM.
- Too flimsy for heavy-duty card bases.
