Aberdeen and Aberdeenshire should have more councillors, while Highland and Moray should have less, the Local Government Boundary Commission has proposed.
The recommendations for a shake-up of Scotland’s 32 councils will be subject to a 12-week public consultation, which started yesterday.
The last set of reviews was completed in 2006 following the introduction of multi-member wards for council elections.
The proposals are based on population distribution, geographical split of ward areas and levels of deprivation.
Under the plans, Aberdeen City would have an extra three members to raise its total to 46, while Aberdeenshire would add two, increasing from 68 to 70.
Highland would lose eight members from 80 to 72, while Moray would drop one, going from 26 to 25.
Argyll and Bute and Western Isles would both lose three, while there would be no change in Orkney or Shetland.
The boundary commission expects to make its recommendations to Scottish Ministers in 2016, and that the resulting wards will be available for the local government elections in May 2017.
Ronnie Hinds, commission chairman, said: “There have been many changes in Scotland since our last reviews, and it is important that electoral arrangements for Scottish councils take account of those changes as part of ensuring effective local democracy.
“We have been encouraged by the discussions we have held with councils on these proposals and look forward to hearing the views of the public over the next 12 weeks”
