Pad dimensions: Regular pads measure 22 x 22 inches or 56 x 56 cm (L x W); center pad measures 19 x 19 inches or 48 x 48 cm (L x W) with a 1.6-inch (4 cm) plastic border on all sides to help prevent overflow. Box is opened and unsure if I’ve used any because I’ve had them over a year. Box is very full so there is a chance there could be 48/49/50 they’re really tightly packed so I can’t count them. I’ve reflected this into the price as I know it’s unhelpful.
