Sarana Tile lists Alexander Pormos as a 12" x 12" glossy porcelain mosaic. The finish gives it a gloss glaze that reflects light back into the room. On the residential side that covers kitchens, entry foyers and open-plan living areas. Commercially it is specified for retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 12" x 12", listed metrically as 30.6x30.6cm. Each sheet covers roughly 1 sq ft. It appears in the Sarana Volume 8 catalogue at page 8. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
