About Admiralty Magnetic Variation Charts

Admiralty Magnetic Variation Charts are essential reference tools produced by the UKHO showing the angular difference between magnetic north and true north (magnetic declination) across different regions. These specialised charts display isogonic lines (lines of equal magnetic variation) and annual rates of change, enabling navigators to accurately convert between true and magnetic bearings. While local magnetic variation information appears on standard navigation charts, this dedicated series provides comprehensive worldwide and regional coverage with greater detail for passage planning and compass correction.

Key Features of Magnetic Variation Charts

• Magnetic Variation Data: Shows current magnetic variation values and isogonic lines across the coverage area.
• Annual Rates of Change: Indicates how magnetic variation changes over time, essential for long-term planning.
• Comprehensive Coverage: Available in worldwide and regional editions for detailed magnetic information.
• Navigation Planning: Essential tool for accurate compass correction and route planning across ocean passages.

Magnetic Variation Charts for Framing & Decorative Wall Art

Authentic Admiralty Magnetic Variation charts make fascinating pieces of nautical wall art, displaying the Earth's invisible magnetic field patterns. However, as these are working navigation charts rather than decorative prints, there are a few practical considerations for those wishing to frame them. Please review the key points below before ordering.

• Chart Dimensions: Most Magnetic Variation charts are printed on DE size paper (approximately 1070 x 715 mm). The actual chart image may be smaller than the paper size, with white borders that can be trimmed if desired. As exact dimensions aren't available until printing, we strongly recommend waiting to receive your chart before ordering a frame.
• Presentation: The chart will be printed from the latest file available. Sometimes this may be more up-to-date than the sample image on this page. Over the past few years the colour palette and general presentation of Admiralty charts has changed as new editions are published. For example, newer editions use a paler yellow for land compared to the traditional deeper 'mustard' colour. If this is of concern please get in touch and we can check the latest thumbnail image.
• Official Markings: Charts will include an official agent's stamp and a line of authentication data in the margin.
• Folded or Unfolded: By default, charts are folded up to three times to a standard size suitable for a ship's chart drawer. If you require an unfolded chart for framing, please select this option when ordering. Both folded and unfolded charts are then rolled for shipping in a tube.

Shipping and Handling

• Printed to Order: Please note that Admiralty charts are not off-the-shelf items. Each one is printed on demand by an official UKHO Print-on-Demand distributor and prepared individually, a process that involves printing, trimming, quality checking, folding, official stamping, and applying a chart number label to the back of the chart. Please check for messages regarding current handling times during the ordering process.
• Urgent Orders: If you are in a hurry, please get in touch with us directly and we will do our very best to accommodate your needs.
• Packaging: Your chart will be shipped rolled in a sturdy cardboard tube. Charts are produced to professional navigation standards where minor creasing, if it occurs, does not affect navigational use. If shipped with Royal Mail we use a standard round tube. If shipped with DPD we use a long rectangular box which carries a slightly higher risk of creasing. Minor creasing can usually be flattened easily with a few hours under some heavy books.
• Returns: Because every chart is printed to order, it is non-returnable unless faulty or damaged. Please ensure the chart you have selected meets your needs before ordering. We are very happy to help with any questions, so please get in touch if you need assistance.
