This post lists the 30 largest church buildings in the world. Whilst claims are made about the relative size of churches many of these claims are not easily substantiated. “Largest” is at best a vague term, which is often not qualified by claimants. Accepted measures of largeness could include area, volume, length, width, height, and/or capacity, although the last is far more subjective. It is important to note therefore that churches may claim to be “the largest” based on only one of these measurements; and thus that there may be several churches that have claims to be “the largest church”. Since there is no official body governing these claims, there is no generally accepted criterion for being “the largest church”.

The list below attempts to rank churches by different (more-or-less) objective criteria, and thus may generate different orders depending on the measure used. Churches for which claims are made but dimensions cannot be found are not included on the below lists. (wikipedia)
