====Along constant longitude====
* The '''longest continuous north–south distance on land''' is {{cvt|7590|km}} along the meridian 99°1'30"E, from the northern tip of Siberia in the Russian Federation ({{Coord|76|13|6|N|99|1|30|E}}), through Mongolia, China, and [[Myanmar]], to a point on the south coast of [[Thailand]] ({{Coord|7|53|24|N|99|1|30|E}}).
** The longest in Africa is {{cvt|7417|km}} along the meridian 20°12'E, from the north coast of [[Libya]] ({{Coord|32|19|0|N|20|12|0|E}}), through [[Chad]], [[Central African Republic]], [[Democratic Republic of the Congo]], [[Angola]], [[Namibia]], and [[Botswana]], to the south coast of [[South Africa]] ({{Coord|34|41|30|S|20|12|0|E}}).
** The longest in South America is the length {{cvt|7098|km}} along the meridian 70°2'W, from the north coast of [[Venezuela]] ({{Coord|11|30|30|N|70|2|0|W}}), through [[Colombia]], [[Ecuador]], [[Peru]], and [[Chile]], to the southern tip of [[Argentina]] ({{Coord|52|33|30|S|70|2|0|W}}).
** The longest in North America is {{cvt|5813|km}} along the meridian 97°52'30"W, from northern [[Canada]] ({{Coord|68|21|0|N|97|52|30|W}}), through the [[United States]], to southern Mexico ({{Coord|16|1|0|N|97|52|30|W}}).
* The '''longest continuous north–south distance at sea''' is {{cvt|15986|km}} along the meridian 34°45'45"W, from the coast of Eastern Greenland ({{Coord|66|23|45|N|34|45|45|W}}) across the [[Atlantic Ocean]] to the [[Filchner-Ronne Ice Shelf]], on the coast of Antarctica ({{Coord|77|37|0|S|34|45|45|W}}). The longest in the Pacific Ocean is {{cvt|15883|km}} along the meridian 172°8'30"W, from the coast of Siberia ({{Coord|64|45|0|N|172|8|30|W}}) to the Ross Ice Shelf in Antarctica ({{Coord|78|20|0|S|172|8|30|W}}).
* The '''meridian that crosses the greatest total distance on land''' (disregarding intervening bodies of water) is still to be determined. It is likely located in the vicinity of 22°E, which is the longest integer meridian that fits that criterion, crossing a total of {{cvt|13035|km}} of land through Europe ({{cvt|3370|km|disp=or}}), Africa ({{cvt|7458|km|disp=or}}), and Antarctica ({{cvt|2207|km|disp=or}}).{{efn|By comparison, the meridian that passes through the [[Great Pyramid of Giza]] in Egypt (31°08'3.69"E) is {{cvt|855|km}} shorter.}} More than 65% of this meridian's length is located on land. The next six longest integer meridians by total distance over land are, in order:
** 23°E: {{cvt|12953|km}} through Europe ({{cvt|3325|km|disp=or}}), Africa ({{cvt|7415|km|disp=or}}), and Antarctica ({{cvt|2214|km|disp=or}})
** 27°E: {{cvt|12943|km}} through Europe ({{cvt|3254|km|disp=or}}), Asia ({{cvt|246|km|disp=or}}), Africa ({{cvt|7223|km|disp=or}}), and Antarctica ({{cvt|2221|km|disp=or}})
** 25°E: {{cvt|12875|km}} through Europe ({{cvt|3344|km|disp=or}}), Africa ({{cvt|7327|km|disp=or}}), and Antarctica ({{cvt|2204|km|disp=or}})
** 26°E: {{cvt|12858|km}} through Europe ({{cvt|3404|km|disp=or}}), Africa ({{cvt|7258|km|disp=or}}), and Antarctica ({{cvt|2196|km|disp=or}})
** 24°E: {{cvt|12794|km}} through Europe ({{cvt|3263|km|disp=or}}), Africa ({{cvt|7346|km|disp=or}}), and Antarctica ({{cvt|2185|km|disp=or}})
** 28°E: {{cvt|12778|km}} through Europe ({{cvt|3039|km|disp=or}}), Asia ({{cvt|388|km|disp=or}}), and Africa ({{cvt|7117|km|disp=or}})
