If you are modelling in HO (1:87) all the OO (1:76) products on Scalescenes.com can easily be resized down to HO scale.

If you are printing on to A4 or Letter, simply enter 87% into your printer's 'Scaling' options, this usually found in the 'Advanced', 'Properties' or 'Options' section of your print window. Consult your printers 'Help Index' for more details.

All card thicknesses can remain as recommended in the instructions.

Happy modelling!
