The delivery of my scale rulers to New Zealand was excellent. I can highly recommend doing business with Building Link Ltd, these people know the value of a customer; I will be coming back.

Scale card for Ordnance Survey maps

Scale card for Ordnance Survey maps

The Rulex Map Scale Card is a handy miniature scale ruler specially designed for Ordnance Survey maps.

When out walking, having located your position on an OS map, rather than judging that the path you want is ‘just down there on the left’ - and then walking right past it – the Map Scale Card will give you the distance to within 25m (at a scale of 1:25000).

Made from durable flexible plastic, the handy credit card size makes it easy to carry in your pack, pocket or wallet.  The most popular OS map scales - 1:25,000, 1:50,000 and 1:40,000 are featured on the front of the card and on the back is a depiction of Naismith’s Rule, helping you to calculate the time that your walk will take.

The Map Scale card is also available for the promotional market.  This means that you can customise the design, feature your own logo and include your own corporate information.  For more information about the Map Scale cards or any other Rulex or personalised products, please contact us at
