Vaginal vs abdominal scan

Robynne • Miscarriage in April 15 at 9 weeks and MC in November 15 at 5 weeks, now expecting our rainbow baby December 2016 🌈🎆
I have a random question but will the baby look bigger on a screen on a vaginal scan vs an abdominal? 
I had an abdominal today and baby was healthy with a strong heartbeat but my oh has said the scan we had at our MC at 6 weeks the baby looked clearer that was an internal scan, although no heartbeat does that sound about right?
