Admiralty Magnetic Dip Chart 5383: The World - Magnetic Dip 2025 and Annual Rates of Change

An official Admiralty Magnetic Dip Chart, printed on demand on quality, watermarked chart paper directly from the UKHO's latest digital files. This specialised chart shows magnetic inclination angles and annual rates of change worldwide for aviation and specialised navigation applications.

About the Admiralty Magnetic Dip Chart

The Admiralty Magnetic Dip Chart is a unique reference tool produced by the UKHO showing magnetic inclination (dip angle) - the angle between the Earth's magnetic field and the horizontal plane. Unlike magnetic variation which affects horizontal compass bearings, magnetic dip represents the vertical component of the Earth's magnetic field. This chart displays isoclinic lines (lines of equal magnetic dip) ranging from +90° at the North Magnetic Pole to -90° at the South Magnetic Pole, with the magnetic equator showing 0° dip. This information is particularly important for aviation navigation systems, compass manufacturing, and specialised magnetic survey work.

Key Features of the Magnetic Dip Chart

• Magnetic Inclination Data: Shows the vertical angle of Earth's magnetic field at locations worldwide.
• Isoclinic Lines: Displays contour lines of equal magnetic dip angle across the globe.
• Annual Rates of Change: Indicates how magnetic inclination changes over time at different locations.
• Aviation Applications: Essential for understanding compass behavior and magnetic reference systems in aircraft.

Magnetic Dip Chart for Framing & Decorative Wall Art

The Admiralty Magnetic Dip Chart makes a unique piece of nautical and scientific wall art, illustrating the three-dimensional nature of Earth's magnetic field. However, as this is a working navigation chart rather than a decorative print, there are a few practical considerations for those wishing to frame it. Please review the key points below before ordering.

• Chart Dimensions: The Magnetic Dip chart is 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.
