Uefa announced on Wednesday it had ended its 30-percent spectator limit in stadiums, allowing host nations to choose their own restrictions at this summer's continent-wide European Championship.
The measure had been in place since last year in reaction to the coronavirus pandemic but travelling supporters are still barred from attending.
"Such a cap is no longer needed and... the decision on the number of permitted spectators should fall under the exclusive responsibility of the relevant competent local/national authorities," European football's governing body said.
"In view of the ongoing travel restrictions and in order to enact reasonable and responsible policies to minimise Covid-19 related risks, the Executive Committee decided to confirm the decision of 1 October 2020 insofar that visiting fans are not allowed to attend Uefa competition matches.
"This is valid until prior to the club competition finals taking place in May 2021," it added.
In another significant decision, five substitutes will be allowed at this summer's Euro 2020 as football continues to grapple with the coronavirus pandemic.
In a statement, European football's governing body said the decision to allow five subs at the delayed tournament had been taken as "the rule is already in place for the World Cup qualification matches that will run from March 2021 to March 2022."
"The reasons for the five-substitutions rule remain valid against the background of national and international football calendars affected by the Covid-19 pandemic," the statement continued.
Uefa added that the rule would also be in place for the Nations League finals in October and its relegation "play-outs" in March next year.
The move to increase the number of substitutes from three to five has already been implemented in the Champions League and Europa League, as well as domestic competitions around the continent.
It came about due to the tight scheduling of the 2020/21 season in Europe, which kicked off late as a result of the pandemic which forced a months-long shutdown of the previous campaign.
