Below are Graeco-Latin squares of different orders and sizes to suit various applications. Hover over image for size info, right-click to download. To keep G-L square's quality, PNG images should not be resized. If a different size is needed, use SVG and export it to PNG/TIFF/JPG of required size. Please keep in mind, that all internal square sizes should be at whole pixel values. This limits final square sizes: order 10 square's dimensions should be a multiple of 30, order 5 — multiple of 15, order 4 — multiple of 12 and order 3 — multiple of 9. Good SVG editors are Inkscape and Libreoffice Draw (free software for Linux, macOS, Windows).

Care should also be taken when exporting to PDF: image compression must be set to lossless or disabled altogether. If application does not provide such PDF export options, please use other application. Scribus and Libreoffice Writer/Impress have a good set of PDF export options. All are free and available for Linux, macOS and Windows.
