Greeting Card Panel Layout Calculator

Greeting Card Panel Layout

Card-making requires precise panel widths so the card folds flat and any printed design aligns correctly.

Common fold styles:

1. Single-fold (most common):

• Width = full sheet
• Two equal panels meet at center fold
• Front and back are same height
• Bottom or side fold both work

2. Tent fold:

• Same as single fold but oriented for landscape (top fold)
• Common for greeting cards displayed standing up

3. Gate fold:

• 4 panels: outer-left, inner-left, inner-right, outer-right
• Outer panels are HALF the width of inner panels
• Typical: outer 25% / inner 25% / inner 25% / outer 25% (for symmetric)
• Outer panels meet at center when closed

4. Z-fold (concertina with single Z):

• 3 equal panels, alternating direction
• Front, middle, back at equal width
• Each panel = sheet width / 3

5. Accordion fold (multi-pleat):

• Equal panels, pleats alternating
• 4 panels: each = width / 4
• 6 panels: each = width / 6
• 8 panels: each = width / 8

6. French fold (double parallel):

• Folded in half, then in half again
• 4 panels per side, all same width
• Width per panel = sheet / 4

7. Pop-up card:

• Single fold or gate fold base
• Internal pop-up tabs/spring need their own calculation

Standard greeting card sizes (US):

Cardstock weight considerations:

• 80-110 lb (216-298 GSM): standard, holds creases well
• 110-140 lb (298-380 GSM): heavyweight, better for gate folds
• Score before folding (use a bone folder or scoring tool) for clean edges
• Heavier paper (over 130 lb) may require pre-creasing

Bleed and trim allowances: For printed cards, add 1/8 inch (3 mm) of bleed on all panels that print to the edge. Trim final card 1/8 inch smaller than your sheet plan if printed at home (printer tolerance).

Common errors to avoid:

1. Forgetting that “card width” means folded width, not sheet width
2. Gate-fold outer panels too wide — they should be HALF inner panel width
3. Accordion folds with odd panel widths — folds won’t close properly
4. Forgetting the 0.5-1mm “swing” allowance in z-fold for clean closure

Precision tools:

• Bone folder: $5-15 (essential)
• Scoring board (Martha Stewart, Crafter’s Companion): $30-60
• Paper trimmer with score blade: $15-50
• Score-and-fold ruler: $10-20
