The most common seating layout at Yankee Stadium for concerts is an end-stage setup with the stage located near Sections 201, 202 and 237. For many concerts there are also slight variations to the layout, which may include General Admission seats, fan pits and B stages.
On the Floor: Sections A1, A2, A3, A4 and more are a part of Floor Seating, which offer some of the closest views of the performers. For many concerts, floor sections are added or removed. These performer-specific adjustments may alter the floor layout and the views from each floor section.
To the Side of the Stage: Most diehard concert-goers will agree that the best concert seats at Yankee Stadium not on the floor are those to the side of the stage in Sections 29, 11, 28 and 12. The view is not head-on like on the floor, but many of the seats are closer to the stage, provide better elevation and are actual stadium seats.
Head-on to the Stage: Seats directly across from the stage, like those in Sections 21A, 19 and 20 provide the most comfortable looks of the performance. Even upper level sections offer unobstructed sitelines. Just keep in mind that you won't be able to see as much detail from these seats as you would if you sat closer to the stage.
Seats behind the stage are occassionally sold: Unless your main objective is to just get in the building, you'll want to completely avoid anything behind the stage - like those in/near or above Sections 201, 202 and 237. It's unlikely the performer will turn around to salute you - and you're more likely to be completely blocked out from seeing the show.
If you're short, only buy floor seats in the first few rows: The most common complaint amongst floor ticketholders is that they can't see the stage because of taller people in front of them. As an alternative, consider side sections near the stage that will still have you close and high enough to see.
Lower level side sections are not created equal: While the side sections closest to the stage are top-notch, side sections farther from the stage may leave you with a cramp in your neck. Sections 120A and 120B are not well-angled towards the stage - leaving you to turn your head for an ideal view. Instead, consider head-on sections in the lower level or even close side seats in the upper level like Sections 227B and 213.
