  • A view of woodland at Kites Hill

    50 acres

    A little smaller than St Michael’s Mount, Cornwall (UK)
    St Michael’s Mount has an area of 0.09 square miles, which is about 57.6 acres.
    So 50 acres is just under the size of St Michael’s Mount. [en.wikipedia.org]

    WLT’s Kites Hill Reserve in the UK covers 48 acres, which is almost exactly the same scale as 50 acres

  • Danjugan Island

    100 acres

    Size of the island of Samson (Scilly Isles, UK), or just under the size of the Vatican City

  • Glastonbury

    1,000 acres

    About twice the size of the Queen Elizabeth Olympic Park in London
    The Olympic Park covers roughly 560 acres, so 1,000 acres is almost double that area.

    Bigger than the entire Glastonbury Festival site
    The main Glastonbury Festival area is usually described as 800 to 900 acres, so 1,000 acres exceeds it comfortably.

  • Battersea Park

    1,500 acres

    Eight times the size of Battersea Park, London
    Battersea Park covers 200 acres, so 1,500 acres is roughly 7.5 times its size. Rounding to eight times works well as an easy public comparison.

    Just under the size of Gibraltar
    Gibraltar measures about 1,600 acres in total area. That makes 1,500 acres slightly smaller—just under the size of Gibraltar.

  • margarita-island-venezuela2-vl

    1,750 acres

    About the size of the island of North Ronaldsay (Orkney, UK)

    Nauru has a land area of 5,200 acres (21 km²), so 5,000 acres is slightly smaller than the world’s smallest republic

  • Estancia La Esperanza Refugio Vida Silvestre

    15,000 acres

    Smaller than San Marino, Italy
    San Marino covers 23.6 square miles, which is 61.2 km².

  • A view of atlantic forest and mountains at REGYA, Brazil

    20,000 acres

    Larger than the Scottish island of Benbecula, UK

  • 100,000 acres

    Just under the size of Barbados
    Barbados has a land area of 439 km², which is 169 sq mi.
    Since 1 square mile = 640 acres, Barbados covers roughly 108,000 acres.
    That makes 100,000 acres just under the size of Barbados.

    Bigger than the English county of Rutland
    Rutland covers 147 sq mi.
    That equates to about 94,000 acres, so 100,000 acres is larger than Rutland.
