Choose cardstock by checking the heaviest weight your printer accepts, then selecting a sheet at or below that limit with a finish that fits the project. Cards, covers and signs all need stiffness, but too much thickness is the usual cause of feeding trouble. Here is how to narrow it down.
Step One: Find Your Printer’s Limit
Open the manual and look for the section on paper types and weights. It often lists a different limit for the main tray and for a rear or single-sheet slot. Write down the highest weight listed for each. If the manual gives pounds and your pack shows gsm, compare the two systems using the packaging, which often shows both.
Step Two: Match Thickness to the Project
| Project | What it needs | What to check |
|---|---|---|
| Greeting cards | Firm but easy to fold | A medium weight; score the fold before bending |
| Report covers | Stiff enough to protect pages | A sheet near the printer’s upper limit |
| Table signs and tags | Stand up or hang without bending | Heavier sheets, possibly fed one at a time |
| Invitations | Smooth surface for text | Smooth or lightly textured finish |
Step Three: Select a Finish
- Smooth uncoated: good for text and simple graphics, and usually friendly to most printers.
- Textured: adds a tactile feel, though fine detail may look softer.
- Coated or glossy: can make images look richer, but check that the sheet suits your ink type and allow extra drying time.
- Colored: pale colors keep text readable; dark colors may reduce contrast.
Step Four: Print a Trial Sheet
- Load a single sheet into the rear or manual slot if your printer has one.
- Select the matching paper type, or the heavy paper option, in the print dialog.
- Print one page and watch how it moves through the machine.
- Check for smudges, curling and uneven feeding.
- If it works, load a few sheets at a time rather than a full tray.
Stop and follow the manual if a sheet sticks. Do not force heavy stock through the path.
If you plan to cut your finished pieces, use a ruler and a sharp craft blade on a mat, and follow the tool’s safety instructions.
FAQ
Can I fold cardstock without cracking it?
Often yes, if you score the fold line first with a ruler and a blunt tool, then fold along the groove. Heavier sheets benefit most from scoring.
Why does my printer reject thick card?
The paper path bends the sheet, and very stiff stock may not turn the corners. Using a straight rear slot, if available, can help within the limits in the manual.
The Short Version
Know your printer’s weight limit, match the sheet to the project, choose a suitable finish and try one page before a batch. Staying inside the manual’s limits is the best way to avoid jams.
