Approximate scale of Playmates ships

[Cerberus]

Hello, I just got some old Playmates ships from a neighbor who was cleaning out his garage. I scored 2 Ent-D, Reliant, Warbird, and a Vor'cha. The problem is most of the stickers have either fallen off, or, are in the process off. Rather than redoing the Ent-Ds as the Enterprise, I want to use diferent registries. After looking online and here, I can find no mention of the scale of these ships. I'm being lazy, rather than measuring them and doing the math, I thought I'd ask. Thanks
