PSA vs BGS vs CGC: Slab Size & Case Comparison

PSA, BGS (Beckett), and CGC are the three major card grading companies, and each one uses a slightly different holder. If you cross-grade or collect across companies, the dimension differences matter — a protector built for a PSA slab won't necessarily fit a BGS or CGC case. Here's the side-by-side comparison.

PSA slab

• Height: 130 mm (5.12 in)
• Width: 86 mm (3.39 in)
• Thickness: 6.0 mm (0.236 in)
• Weight: ~28–30 g
• Shape: rectangular, rounded corners, ultrasonic-welded seam

BGS (Beckett) slab

• Height: 135 mm (5.31 in)
• Width: 91 mm (3.58 in)
• Thickness: 7.5 mm (0.295 in)
• Weight: ~38–42 g
• Shape: rectangular with thicker shell and inner sub-grade card stock

CGC slab

• Height: 130 mm (5.12 in)
• Width: 89 mm (3.50 in)
• Thickness: 6.5 mm (0.256 in)
• Weight: ~30–33 g
• Shape: rectangular, square corners, tamper-evident inner well

Side-by-side summary

• PSA is the smallest and slimmest of the three.
• CGC is roughly PSA-sized but slightly wider and ~0.5 mm thicker.
• BGS is the largest in every dimension — taller, wider, and noticeably thicker.

Which protector should you buy?

SlabGuards are designed specifically for the PSA standard slab footprint. If the majority of your collection is PSA, SlabGuard is built for you. For mixed collections, label your storage boxes by company so the right protector lives with the right slab.
