What Does Coverage Length Mean In Life Insurance? 
By the wording of the question , I would assume that it means the amount of time that the policy will remain inforce if the premiums are paid as per the policy agreement . This would typically be part of a term policy which normally run 10 , 20 or 30 year terms . Please remember every policy is diffent . Read your policy completely to understand the coverage and the exclusions or call your local agent to discuss the policy coverage and exclusions .
